In July of 1972, Davy Jones headlined a Saturday afternoon TV special called POP that served as a pilot for a show to rival Dick Clark's AMERICAN BANDSTAND for teens. I never heard of it because locally it was pre-empted by a football game.
POP also featured, among others, The Osmond Brothers and the Mike Curb Congregation (pre-Kathy Coleman). Here's some info I found on the show. Maybe YOU saw it?
