Problem: Edouard Louis Joseph, baron Merckx (Dutch pronunciation: ['merks]; born 17 June 1945), better known as Eddy Merckx, is a Belgian former professional road and track bicycle racer who is widely seen as the most successful rider in the history of competitive cycling. His victories include an unequalled eleven Grand Tours (five Tours of France, five Tours of Italy, and a Tour of Spain), all of the five Monuments, three World Championships, the hour record, every major one-day race other than Paris-Tours, and extensive victories on the track. Born in Meensel-Kiezegem, Brabant, Belgium, he grew up in Woluwe-Saint-Pierre where his parents ran a grocery store. He played several sports, but found his true passion in cycling.

An illness prevented Merckx from taking part in the Milan-San Remo at the start of the 1973 calendar. During a span of nineteen days, Merckx won four classics including Omloop Het Volk, Liege-Bastogne-Liege, and Paris-Roubaix. He decided to race the Vuelta a Espana and the Giro d'Italia, instead of racing the Tour de France. He won the opening prologue of the Vuelta to take an early lead. Despite Ocana's best efforts, Merckx won a total of six stages on his way to his only Vuelta a Espana title. In addition to the general classification, Merckx won the race's points classification and combination classifications. Four days after the conclusion of the Vuelta, Merckx lined up to start the Giro d'Italia. He won the opening two-man time trial with Roger Swerts and the next day's leg as well. Merckx's primary competitor, Fuente, lost a significant amount of time during the second stage. He won eighth stage that featured a summit finish to Monte Carpegna despite Fuente attacking several times on the ascent. Fuente tried attacking throughout the race of the race, but was only able to make time gains on the race's penultimate stage. Merckx won the race after leading from start to finish, a feat only previously done by Alfredo Binda and Costante Girardengo. He also became the first rider to win the Giro and Vuelta in the same calendar year. The UCI Road World Championships were held in Barcelona, Spain in 1973 and contested on the Montjuich circuit. During the road race, Merckx attacked with around one hundred kilometers left. His move was marked by Freddy Maertens, Gimondi, and Ocana. Merckx attacked on the final lap, but was reeled in by the three riders. It came down to a sprint between the four, of which Merckx came in last and Gimondi in first. Following the road race, Merckx won his first Paris-Brussels and Grand Prix des Nations. He won both legs of A travers Lausanne, as well as the Giro di Lombardia, but a doping positive disqualified him. He closed the season with over fifty victories to his credit.

Problem: Chicago is an American rock band formed in 1967 in Chicago, Illinois as The Chicago Transit Authority before shortening the name in 1970. The self-described "rock and roll band with horns" began as a politically charged, sometimes experimental, rock band and later moved to a predominantly softer sound, generating several hit ballads. The group had a steady stream of hits throughout the 1970s and 1980s. Since at least 2008, Billboard has shown Chicago to be the "greatest of all time" American band in singles chart success, and since 2015, the "greatest of all time" American band in album chart success as well.

The original band membership consisted of saxophonist Walter Parazaider, guitarist Terry Kath, drummer Danny Seraphine, trombonist James Pankow, trumpet player Lee Loughnane, and keyboardist/singer Robert Lamm. Parazaider, Kath, Seraphine, Pankow and Loughnane met in 1967 while students at DePaul University. Lamm was recruited from Roosevelt University. The group of six called themselves "The Big Thing", and played top 40 hits. Realizing the need for both a tenor to complement baritones Lamm and Kath, and a bass player because Lamm's use of organ bass pedals did not provide "adequate bass sound", they added local tenor and bassist Peter Cetera. While gaining some success as a cover band, the group began working on original songs. In June 1968, at manager James William Guercio's request, The Big Thing moved to Los Angeles, California, and signed with Columbia Records. The band changed its name to "Chicago Transit Authority". It was while performing on a regular basis at the Whisky a Go Go nightclub in West Hollywood that the band got exposure to more famous musical artists of the time. Subsequently, they were the opening act for Janis Joplin and Jimi Hendrix. As related to group biographer, William James Ruhlmann, by Walt Parazaider, Jimi Hendrix once told Parazaider, "'Jeez, your horn players are like one set of lungs and your guitar player is better than me.'" Their first record (April 1969), the eponymous Chicago Transit Authority, is a double album, which is rare for a band's first release. The album made it to No. 17 on the Billboard 200 album chart, sold over one million copies by 1970, and was awarded a platinum disc. The album included a number of pop-rock songs - "Does Anybody Really Know What Time It Is?", "Beginnings", "Questions 67 and 68", and "I'm a Man" - which were later released as singles. For this inaugural recording effort the group was nominated for a Grammy Award for 1969 Best New Artist of the Year. According to Peter Cetera, the band was booked to perform at Woodstock in 1969, but promoter Bill Graham, with whom they had a contract, exercised his right to reschedule them to play at the Fillmore West on a date of his choosing, and he scheduled them for the Woodstock dates. Santana, which Graham also managed, took Chicago's place at Woodstock, and that performance is considered to be Santana's "breakthrough" gig. A year later, in 1970, when he needed to replace headliner Joe Cocker, and then Cocker's intended replacement, Jimi Hendrix, Graham booked Chicago to perform at Tanglewood which is considered by some to be a "pinnacle" performance. After the release of their first album, the band's name was shortened to Chicago to avoid legal action being threatened by the actual mass-transit company of the same name.
