Wikipedia:
Songs for the album Jazz were recorded in Nice, France and Montreux, Switzerland in 1978.
The band attended the Montreux Jazz Festival, which likely inspired the title of the album. There they ran into David Bowie who was working on his 1979 album Lodger between tour dates. Bowie convinced them to record at Mountain Studios in Montreux.
Production on the album was moved from Nice to Montreux the day after the jazz festival. On 19 July, May’s 31st birthday, the band attended the 18th stage of the 1978 Tour de France, which inspired Freddie Mercury to write the lead single Bicycle Race.
The two songs Fat Bottomed Girls and Bicycle Race were released together on a double A-side single, and both songs refer to each other. Near the end of Fat Bottomed Girls, the song references Bicycle Race, with Mercury shouting, “Get on your bikes and ride!” Bicycle Race reciprocates with the line “fat bottomed girls, they’ll be riding today”.
