After Dick Clark moved American Bandstand to a Saturday afternoon berth in 1963, ABC was looking for another music series to fill the after-school void. In 1965, Clark obliged them with Where The Action Is.
The series began as a summer replacement, airing at 2 pm (ET) before shifting to an after-school airtime at 4:30 in the fall. However, the series didn't last very long, cancelled in March 1967 after less than 2 years on the air. Clark, of course, was hardly done. Bandstand soldiered on into the late 80's, and a year after Action ended, Clark created It's Happening, and its Saturday afternoon sister series, Happening '68, but both shows met the same fate.
Clark serves as an off-camera narrator/announcer rather than host. Paul Revere & the Raiders, who'd later host Happening '68, were the house band for the first year, which would explain why they were enough of a lure to merit a cameo appearance on Batman early in that series' run.
Now, I never got to see the show, since I was but a wee lad, but if you were a fan of Bandstand, this does trod the same ground. I will not offer a rating, just to be fair.
