The Rays was an American group formed in New York in 1955, and active in the early 1960s. They first recorded for Chess Records. Their biggest hit single was "Silhouettes," a moderately-slow doo-wop piece of pop music that reached #3 on the Billboard Top 100 in 1957 on Cameo after being initially released on the small XYZ Records. It sold over one million copies, and was awarded a gold disc. The song was written by Bob Crewe and Frank Slay, Jr. Also on XYZ, they had a minor hit with "Mediterranean Moon" a mid-chart hit with "Magic Moon" (by this time, XYZ was being nationally distributed by London Records).

They also recorded the original version of "Daddy Cool", which was used as part of a medley with Little Richard's "The Girl Can't Help It" for U.K. band Darts which made the U.K charts (#6) in 1977. The song also lent its name to the Australian band Daddy Cool, who recorded the song in 1971.
