Guitarist Dean DeLeo explained the song title to Musicradar.com: "There's a very good reason why it's titled Fast As I Can, because it's the fastest song we ever recorded. I think it's something like 196bpms. That's like, way fast!"
Dean DeLeo discussed his contribution to this song: "Another highpoint for me as a guitar player. I was able to express myself with a lot of groovy country licks, using a clean Strat tone. The solo really gets me off. For the chorus I use a Danelectro, and the solo is a Strat and the verses are a Les Paul - I really mix it all up here. Fun guitar stuff."
Stephens Stills played timbales on the Bee Gees hit, "You Should Be Dancing." He was in the next door studio laying down a Crosby, Stills and Nash album and could hear Saturday Night Fever being recorded. Stills recognized its potential to be a monster hit and he wanted to contribute.
