The Cham-Cham
"The Cham-Cham" is the 25th episode of "Thunderbirds", a British Supermarionation television series created by Gerry and Sylvia Anderson and filmed by their production company AP Films (APF). The penultimate episode of "Thunderbirds" Series One, it was written and directed by Alan Pattillo and first broadcast on 24 March 1966 on ATV Midlands. Set in the 2060s, "Thunderbirds" follows the exploits of International Rescue, an organisation that uses technologically-advanced rescue vehicles to save human life. The main characters are ex-astronaut Jeff Tracy, founder of International Rescue, and his five adult sons, who pilot the  organisation's main vehicles: the "Thunderbird" machines. "The Cham-Cham" opens with a United States Air Force plane being shot down during a radio broadcast of the instrumental "Dangerous Game" by popular musical group the Cass Carnaby Five. International Rescue suspect sabotage, and Lady Penelope, Tin-Tin and Parker travel to the Swiss Alps to investigate the band's current tour venue, the mountain resort Paradise Peaks. There, they discover that the RTL2 attacks are being co-ordinated with the aid of an advanced computer called a "Cham-Cham". Filmed in late 1965, "The Cham-Cham" has a show business  theme and was written in the style of classic Hollywood musicals. It features several innovations in APF's use of marionette puppets. One scene features the Penelope character performing a slow dance, which was a challenge to film due to the difficulty in moving Supermarionation puppets convincingly. "The Cham-Cham" is also the first episode of any Supermarionation series to show characters skiing. "Dangerous Game", the focus of the episode's soundtrack, was devised as a Latin rhythm by series composer Barry Gray. Singer Ken Barrie recorded a lyrical version but this is not heard in the finished episode. "The  Cham-Cham" has been well received by commentators, drawing particular praise for its production design and soundtrack. Sylvia Anderson considered the plot "far-fetched" but valued the episode for its "charm" and Swiss Alps setting. An audio adaptation of the episode, narrated by David Graham as Parker, was released in March 1967 as the Century 21 mini-LP "Lady Penelope". Plot. USAF planes flying missile shipments out of Matthews Field air base have been shot down by enemy fighters shortly after take-off. On Tracy Island, Alan (voiced by Matt Zimmerman) notes that each attack has occurred while popular band  the Cass Carnaby Five have been performing their hit instrumental "Dangerous Game" on live radio. He and Brains (voiced by David Graham) examine a recording of the latest broadcast to determine whether the music contains a hidden code that is being used to co-ordinate the attacks. Meanwhile, Jeff (voiced by Peter Dyneley) assigns Lady Penelope, Tin-Tin and Parker (voiced by Sylvia Anderson, Christine Finn and David Graham) to investigate Paradise Peaks, a mountain-top hotel in the Swiss Alps that is currently playing host to Cass Carnaby and his group. The agents go undercover, with Penelope posing as  a singer called "Wanda Lamour" and Parker securing a job as a waiter. They learn that Carnaby's manager, the mysterious Mr Olsen, often alters the arrangement of "Dangerous Game" before each new broadcast and that he is expecting to receive a message the following day. In the morning, Penelope and Tin-tin ski down the mountain to Olsen's chalet and film him operating a strange machine that is decoding musical sounds into text stating the time of the next missile shipment. They deduce that he is issuing orders for the next attack and start back to Paradise Peaks  to alert Jeff. Realising that he has been observed, Olsen telephones his associate Banino, a waiter at the hotel, with orders to kill Penelope and Tin-Tin. Banino goes outside with a sniper rifle and prepares to shoot the women before they reach the hotel. However, he is thwarted by Parker, who overheard the phone conversation and grabs the rifle, upsetting Banino's aim. In their struggle, the men lose their balance and tumble down the mountain together, forming a giant snowball in the process. Banino is knocked out but Parker emerges unscathed. On Tracy Island, Brains identifies Olsen's  machine as a Cham-Cham, an ultrasonically-sensitive computer that Olsen is using to send coded radio transmissions. Jeff relays this information to Washington, D.C., but the Matthews Field commander is sceptical and refuses to postpone the next shipment. That night, the Cass Carnaby Five begin performing Olsen's latest arrangement of "Dangerous Game". The shipment seems doomed until Penelope, in the guise of Wanda Lamour, appears on stage and sings a lyrical version, devised by Brains, containing a new set of coded instructions. Decoding the broadcast, the personnel at the enemy air base unwittingly direct their fighters to overfly  Matthews Field. Arriving in "Thunderbird 1", Scott (voiced by Shane Rimmer) alerts the commander and USAF fighters are launched to shoot down the hostiles. Fearing Olsen's retribution, Jeff dispatches Virgil (voiced by David Holliday) and Alan to Paradise Peaks in "Thunderbird 2" to bring Penelope, Tin-Tin and Parker home. As the trio leave the hotel in a cable car, Olsen cuts the lines behind them, causing the car to speed out of control down the mountain. "Thunderbird 2"s magnetic grabs cannot get a purchase on the car, so Virgil and Alan release a set of guide cables . Climbing onto the roof, Parker hooks the cables with the handle of Penelope's umbrella and attaches them to the car. Virgil and Alan fire "Thunderbird 2"s retro-rockets, bringing the car to a halt but also throwing Parker off the roof. He uses the umbrella to parachute safely to the ground. Penelope, Tin-Tin, Parker and the Tracys return to Paradise Peaks, where Cass treats them to a private piano recital of "Dangerous Game". Production. Filmed in November and December 1965, "The Cham-Cham" was the second-to-last episode of "Thunderbirds" Series One to be produced. Scriptwriter Alan  Pattillo created its show business plot and the exotic setting of Paradise Peaks in an attempt to emulate classic Hollywood musicals. Penelope's alias, Wanda Lamour, was named after the actress and singer Dorothy Lamour and Wanda Webb, one of APF's puppet operators. APF had always found it difficult to make its puppets walk convincingly, so rarely showed this action openly on-screen. Instead, the puppet operators created an illusion of walking by holding the puppets' legs (which were kept out of shot) and moving the puppets up and down using a "bobbing" action. For the scene in "The  Cham-Cham" where Penelope glides across the Paradise Peaks ballroom while singing "Dangerous Game", Webb worked the puppet from the stage while fellow operator Christine Glanville controlled its wired top portion from an overhead gantry. Gerry Anderson believed that Penelope and Tin-Tin's trip to Olsen's lodge looked suitably realistic, despite APF never having shown puppets skiing prior to this episode. Anderson himself conceived the "ski thrusters" used by the characters to ascend the mountain during their journey back to Paradise Peaks, in part to remove the need for the puppets to walk. Praising Bob Bell's production  design, Anderson commented that the episode "gave [APF's] art and design departments a chance to show what they could really do, and they didn't let us down." Composer Barry Gray devised "Dangerous Game" as a Latin rhythm. Originally all performances by the Cass Carnaby Five were to have been a lyrical version sung by Ken Barrie, but for the finished episode this was replaced with a variety of instrumental versions. Sylvia Anderson based her singing voice on that of Marlene Dietrich. The shots of Penelope and Tin-Tin skiing to Olsen's chalet are accompanied by an incidental  track called "Happy Flying" that was originally composed for the "Supercar" episode "Amazonian Adventure". As with "Attack of the Alligators!", which had been filmed immediately prior, the technical complexity of "The Cham-Cham" caused production to finish behind schedule and considerably over-budget. To make up for the lost time and extra costs, the scriptwriters turned the final episode of Series One into a clip show. That episode, "Security Hazard", made extensive use of flashbacks to earlier instalments to reduce the amount of new footage that needed to be filmed. Reception. Sylvia Anderson considered "The Cham-Cham" one of the  series' best episodes and a rival to "Attack of the Alligators!" in terms of quality. On her website, she commented: "Even though the plot is far-fetched, it has charm and, because of the lovely Swiss mountain setting, has credibility." Gerry Anderson biographers Simon Archer and Marcus Hearn describe "The Cham-Cham" as "perhaps the most lavish-looking episode of the series", calling the scenes of Penelope and Tin-Tin skiing and Penelope singing "unforgettable images". Hearn, in his book "Thunderbirds: The Vault", calls the episode one of "Thunderbirds" "most entertaining" due to its focus on Penelope and Parker as  well as its use of "one of the most exotic locations in the series". Tom Fox of "Starburst" magazine rates the episode 4 out of 5, describing the plot as "tenuous" but believing this to be redeemed by the production design and the scenes of the cable car rescue. Like Archer and Hearn, he is entertained by Parker's umbrella descent. Ian Fryer considers the premise to be inspired by the first episode of "The Sentimental Agent", "All That Jazz" (1963), in which a band are found to be sending information to spies. He praises the "confidence" of "The Cham -Cham", calling it a "triumph" for art director Bob Bell and writing that although the story has "occasional moments of silliness", "everything about the production works perfectly." He believes that the episode is proof of Supermarionation's ability to "present glamour convincingly on-screen" and represents the "absolute pinnacle of what [the Andersons] achieved with puppetry". According to commentator Alistair McGown, the story was influenced by "Road to..." comedy films and the spy series "The Avengers". He writes that while the plot "may be flimsy in places", the overall episode is a "gorgeous confection" with the skiing and dancing sequences  paying "impressive attention to detail". Both McGown and Hearn call the skiing scenes "charming". Stephen La Rivière, author of "Filmed in Supermarionation: A History of the Future", praises the episode's technical standards, remarking that the skiing and dancing sequences "[fly] in the face of what puppets can and can't do." He sums up "The Cham-Cham" as a "glorious example of "Thunderbirds" at its best, combining all the elements that made the show so popular: the characters, the adventure, the rescues and, of course, the humour." He further argues that the humour has intergenerational appeal, stating that Parker 's double entendres are counterbalanced by overt slapstick moments such as the character's "Mary Poppins"-style descent using Penelope's umbrella. In a review of the CD release of the "Thunderbirds" soundtrack, Morag Reavley of BBC Online describes Sylvia Anderson's singing as "slinky, sexy and slightly off-key, like a hung-over Zsa Zsa Gabor". Heather Phares of AllMusic considers "Dangerous Game" to be a highlight of the release, commenting that while the instrumental version "[reflects] the Sixties' ongoing fascination with exotica and Latin pop", its lyrical counterpart "could be a kissing cousin to seductive spy themes like 'Goldfinger '." McGown calls Anderson's conscious imitation of Marlene Dietrich her "campest moment" voicing Penelope. Media historian Nicholas J. Cull interprets "The Cham-Cham" as a piece of Cold War-inspired fiction, noting the "Central/Eastern European accents" of the enemy airbase personnel. References. Works cited
