The Radiants

The Radiants were formed in Chicago in 1960, where its members met singing in the youth choir of Greater Harvest Baptist Church. They performed both gospel and secular tunes, the latter of which were written by leader Maurice McCallister. While attempting to land a record deal, they found that labels weren't interested in gospel groups anymore, and concentrated on secular tunes, eventually lanning a deal with Chess Records. Billy Davis produced their early records, including the first, "Father Knows Best" b/w "One Day I'll Show You", which was a regional hit in Cleveland in 1962.

Several more singles for Chess followed, but didn't sell well, and by 1964 the group had more or less broken up. McCallister and baritone Wallace Sampson continued on as a trio with new member Leonard Caston, Jr. (son of Leonard Caston). With this lineup they had their biggest hit, 1964's "Voice Your Choice". The follow-up, "Ain't No Big Thing", was also a hit.
