Background: Skyhooks were an Australian rock band formed in Melbourne in March 1973 by mainstays Greg Macainsh on bass guitar and backing vocals, and Imants "Freddie" Strauks on drums. They were soon joined by Bob "Bongo" Starkie on guitar and backing vocals, and Red Symons on guitar, vocals and keyboards; Graeme "Shirley" Strachan became lead vocalist in March 1974. Described as a glam rock band, because of flamboyant costumes and make-up, Skyhooks addressed teenage issues including buying drugs "Carlton (Lygon Street Limbo)", suburban sex "Balwyn Calling", the gay scene "Toorak Cowboy" and loss of girlfriends "Somewhere in Sydney" by namechecking Australian locales.
Context: For Skyhooks, the replacement of Hill by Strachan was a pivotal moment, as Strachan had remarkable vocal skills, and a magnetic stage and screen presence. Alongside Macainsh's lyrics, another facet of the group was the twin-guitar sound of Starkie and Symons. Adopting elements of glam rock in their presentation, and lyrics that presented frank depictions of the social life of young Australia in the 1970s, the band shocked conservative middle Australia with their outrageous (for the time) costumes, make-up, lyrics, and on-stage activities. A 1.2 metre (4 ft) high mushroom-shaped phallus was confiscated by Adelaide police after a performance. Six of the ten tracks on their debut album, Living in the 70's, were banned by the Federation of Australian Commercial Broadcasters for their sex and drug references, "Toorak Cowboy", "Whatever Happened to the Revolution?", "You Just Like Me Cos I'm Good in Bed", "Hey What's the Matter", "Motorcycle Bitch" and "Smut". Much of the group's success derived from its distinctive repertoire, mostly penned by bass guitarist Macainsh, with an occasional additional song from Symons--who wrote "Smut" and performed its lead vocals. Although Skyhooks were not the first Australian rock band to write songs in a local setting--rather than ditties about love or songs about New York or other foreign lands--they were the first to become commercially successful doing so. Skyhooks songs addressed teenage issues including buying drugs ("Carlton (Lygon Street Limbo)"), suburban sex ("Balwyn Calling"), the gay scene ("Toorak Cowboy") and loss of girlfriends ("Somewhere in Sydney") by namechecking Australian locales. Radio personality, Billy Pinnell described the importance of their lyrics in tackling Australia's cultural cringe: [Macainsh] broke down all the barriers [...] opening the door for Australian rock 'n' roll songwriters to write about local places and events. He legitimised Australian songwriting and it meant that Australians became themselves. The first Skyhooks single, "Living in the 70's", was released in August, ahead of the album, and peaked at #7 on the Australian Kent Music Report Singles Charts. Living in the 70's initially charted only in Melbourne upon its release on 28 October 1974. It went on to spend 16 weeks at the top of the Australian Kent Music Report Albums Charts from February to June 1975. The album was produced by Wilson, and became the best selling Australian album, to that time, with 226,000 copies sold in Australia. Skyhooks returned to the Sunbury Pop Festival in January 1975. They were declared the best performers by Rolling Stone Australia and The Age reviewers, and Gudinski now took over their management. The second single, "Horror Movie", reached #1 for two weeks in March. The band's success was credited by Gudinski with saving his struggling Mushroom Records and enabled it to develop into the most successful Australian label of its time. The success of the album was also due to support by a new pop music television show Countdown on national public broadcaster ABC Television, rather than promotion by commercial radio. "Horror Movie" was the first song played on the first colour transmission of Countdown in early 1975. Despite the radio ban, the ABC's newly established 24-hour rock music station Double Jay chose the album's fifth track, the provocatively titled "You Just Like Me Cos I'm Good in Bed", as its first ever broadcast on 19 January.

Background: Charles "Pete" Conrad Jr. (June 2, 1930 - July 8, 1999), (Captain, USN), was an American NASA astronaut, aeronautical engineer, naval officer and aviator, test pilot, and during the Apollo 12 mission became the third man to walk on the Moon. Conrad was selected in NASA's second astronaut class. He set an eight-day space endurance record along with his Command Pilot Gordon Cooper on his first spaceflight, the Gemini 5 mission. Conrad also commanded the Gemini 11 mission.
Context: Conrad retired from NASA and the Navy in 1973, and went to work for American Television and Communications Company. He started as the Vice President of Operations and Chief Operating Officer. Conrad was in charge of the operation of existing systems and the national development of new cable television systems. In 1976, he accepted a position with McDonnell Douglas as a Vice President and consultant. In 1978, he became Vice President of marketing and was responsible for the commercial and military sales of Douglas Aircraft Company. After an engine fell off a McDonnell Douglas DC-10, causing it to crash with the loss of all passengers and crew in 1979, Conrad spearheaded McDonnell Douglas's ultimately unsuccessful efforts to allay the fears of the public and policymakers, and save the plane's reputation. In 1980, he was promoted to Senior Vice President of marketing. From 1982 to 1984, Conrad served as the Senior Vice President of marketing and product support. He was appointed Staff Vice President of International Business Development in 1984. During the 1990s he consulted for the Delta Clipper experimental single-stage-to-orbit launch vehicle. He became Vice President of project development in 1993. On February 14, 1996, Conrad was part of the crew on a record-breaking around-the-world flight in a Learjet owned by cable TV pioneer, Bill Daniels. The flight lasted 49 hours, 26 minutes and 8 seconds. Today the jet is on permanent static display at Denver International Airport's Terminal C. A month before he died, Conrad appeared on ABC News Nightline and said, "I think the Space Shuttle is worth one billion dollars a launch. I think that it is worth two billion dollars for what it does. I think the Shuttle is worth it for the work it does." In the last interview he gave before his death, Conrad sat down for PBS's Nova series and discussed where he felt the future direction of space travel should go. He considered returning to the Moon "a waste of taxpayer money", but recommended missions to Mars and asteroids. In 2006, NASA posthumously awarded him the Ambassador of Exploration Award for his work for the agency and science.
