“Rock Your Baby” was written by Richard Finch and Harry Wayne Casey of KC and the Sunshine Band.
The problem was, neither could sing the high notes required in the song. At the time, George McCrae was acting as manager for his wife, singer Gwen McCrae.
The original intention was that Gwen should record it, but she was late for the session and George recorded alone.
“Rock Your Baby” became one of the first hits of the disco era in 1974, selling an estimated eleven million copies worldwide.
Rolling Stone magazine voted it the #1 song of the year in 1974.
