Raydio was a funk and R&B vocal group formed in 1977, by Ray Parker Jr., with Vincent Bohnam, Jerry Knight, and Arnell Carmichael.

The group scored their first big hit in 1978 with "Jack and Jill", which was taken from their debut, self-titled album. The song peaked at #8 on the U.S. Billboard Hot 100 chart, and reached #11 in the UK Singles Chart, earning a gold record in the process. Their successful follow-up hit, "You Can't Change That" was released in 1979, and lifted from their Rock On album. The single made it up to #9 on the Billboard chart that year.
