@eoe,
I recall Hullabaloo and Shindig! On Shindig often times Bobby Sherman and Paul Revere and the Raiders appeared on those shows. I just learned that, believe it or not, actress Teri Gar was a regular Shindig dancer.
"The series house band, the Shin-diggers (later renamed the Shindogs), featured a young Glen Campbell, Joey Cooper, Chuck Blackwell (drums), Billy Preston, James Burton, Delaney Bramlett, Larry Knechtel (on bass) and pianist Leon Russell.
The Blossoms, an all-female vocal group featuring Darlene Love, backed up many of the performers and were occasionally featured in spotlight performances. The Wellingtons were a trio of male singers who performed on their own and as backup singers. Donna Loren, Jackie DeShannon and Bobby Sherman were also regular vocalists on the series."
