Rock Your Baby by George McCrae

"Rock Your Baby" is the debut single by George McCrae. Written and produced by Harry Wayne Casey and Richard Finch of KC and the Sunshine Band, "Rock Your Baby" was one of the landmark recordings of early disco music. A massive international hit, the song reached number one on the Billboard Hot 100 singles chart in the United States, spending two weeks at the top in July 1974, number one on the R&B singles chart, and repeating the feat on the UK Singles Chart, spending three weeks at the top of the chart in July 1974. Having sold 11 million copies, it is one of the fewer than 40 all-time singles to have sold 10 million (or more) physical copies worldwide.The backing track for the record was recorded in 45 minutes as a demo and featured guitarist Jerome Smith of KC and the Sunshine Band, with Casey on keyboards and Finch on bass and drums. It was also one of the first records to use a drum machine, an early Roland rhythm machine. The track was not originally intended for McCrae but he happened to be in the studio, added a vocal and the resulting combination of infectious rhythm and falsetto vocals made it a hit. Music critic Robert Christgau has described the song as "irresistibly Memphis-cum-disco-with-a-hook".The chord progression of John Lennon's number-one single "Whatever Gets You thru the Night", released a few months later, bears a great resemblance to the one found in "Rock Your Baby". Lennon later admitted to using the song as an inspiration. ABBA's Benny Andersson and Björn Ulvaeus have also cited the song as an inspiration for the backing track of their 1976 smash hit "Dancing Queen". The song was covered by indie rock band The House of Love for the 1992 compilation album Ruby Trax. In the same year, the British dance group KWS' cover of "Rock Your Baby" reached number eight in the UK Singles Chart.
