Most of the music for this song was written by drummer Carmine Appice, who had recently joined Stewart's band. Appice told Songfacts
: "We were in the studio and 'Miss You
' by The Rolling Stones was a big hit. Rod was always a guy that used to listen to what was going on around him. He was always looking at the charts and listening. He was a big fan of The Rolling Stones, so when they came out with "Miss You
," disco was really big at the time, so he wanted to do some kind of disco-y song, something like 'Miss You,' nothing like Gloria Gaynor.
With the band, he would always tell us, 'I want a song like this' or 'I want a song like that,' so I went home and I came up with a bunch or chords and a melody. I presented it to him via a friend of mine, Duane Hitchings, who is a songwriter who had a little studio. We went in his studio with his drum machines and his keyboards, and he made my chords sound better. We gave Rod a demo of the verses and the bridge, and Rod came up with the chorus. We played it with the band many, many ways before we got the correct arrangement with Tom Dowd. Unfortunately, they put so much stuff on it that it dwarfed the sound of the band. It made the band sound smaller because it had strings and two or three keyboard players, congas, and drums. When we were doing it, we thought it was going to be more like The Rolling Stones with just the band playing it. It came out and went to #1 everywhere."
