The show was another step in the then-current trend of entertainment programs that targeted the teenage audience by focusing on pop music, following in the footsteps of Shindig!
The program had its own stable of performers, most notably Paul Revere & the Raiders, who served as the de facto house band.
Easily identified by their Revolutionary War costumes, the band had several Top 40 hits in the '60s thanks in part to the exposure they received on "Where The Action Is".
Their lead singer, Mark Lindsay, with his signature ponytail, became one of the most popular teenage idols of the decade, gracing the covers of countless teen magazines.
The Raiders also recorded the "Action" theme song for their 1965 album "Just Like Us" for which Dick Clark wrote the liner notes.
However, members of the program's mainstay band Paul Revere and the Raiders (with lead vocalist Mark Lindsay) hosted very similar follow-up shows: both Revere and Lindsay hosted Happening '68, a Saturday afternoon follow-up to American Bandstand, and a weekday version of the same show, It's Happening, from 1968 to 1969.
