The Young Americans sessions mostly concluded by late 1974. During this time, Bowie was staying in New York, where he met John Lennon. The pair jammed together, leading to a one-day session at Electric Lady Studios in January 1975. There, Carlos Alomar had developed a guitar riff for Bowie's cover of "Footstompin'" by The Flairs, which Bowie thought was "a waste" to give to a cover. Lennon, who was in the studio with them, sang "ame" over the riff, which Bowie turned into "Fame" and he thereafter wrote the rest of the lyrics to the song. Read more on Last.fm.
