One of the first hits of the disco era, this sold over 11 million copies worldwide. The song was written by Harry Wayne Casey
and Richard Finch of KC & The Sunshine Band, and it formed the basis for their wildly successful writing and performing partnership which yielded five more US #1 hits and pioneered the disco sound. Casey and Finch worked for TK Records, which was a distributor and a studio, complete with a house band that would become KC & The Sunshine Band. One of the artists who recorded at TK was Timmy Thomas, who had a hit with "Why Can't We Live Together?"Finch told Songfacts
: "His organ was left up in the studio, and 'Rock Your Baby' became born unto this crazy drum machine that was inside of this Lowry organ that he left there. I used to use that as a tempo map, and I would play along with the drum machine. In the beginning it would hide my errors, but it would also teach me to be a better drummer, because I was paying attention to it that closely. Then we would build on that. We had a 1-inch 8-track machine and I had a cheap Japanese bass. We were just recording and recording and recording. And one night, this one track came out like better than anything else. It was like God was in the building or something - we had been blessed. It was like the hunger and desire was so incredibly overwhelming that some magical moment happened in there. We knew to build on that track.
There were a bunch of records coming out at that point. Hues Corporation had a song called 'Rock The Boat
,' and Harry and I were also paying attention to the chart actions at clubs, because club records, according to Henry's direction, were doing better than just regular R&B Records. Back then you could sneak into a club and they didn't check your ID, so Harry and I would once in a while go sneak into the local clubs. There was one on Southwest 8th Street in Miami, Florida, that played dance music. We'd go in there for about an hour or two until it got to be way too late for us to be there. And we'd pay attention to what brought the people to the dance floor, and what made them sit down. So we started gearing ourselves to writing more in that direction. 'Rock Your Baby' was inspired by the gathering of all that information."
