I lived half way between Baltimore and Philly when this show was in it's hayday out of Philly.
I went back and forth between this and the regional hit show hosted by Buddy Dean out of Baltimore.
Dick Clark had the better acts. Dave Clark integrated the show rather than leave the air as Buddy Dean did.
Dick Clark had an eye for up and coming groups.
He also had the advantage of one of the hot spots of talent...South Philly. A number of the male teen idols of the day came from there and were happy to be showcased locally and later nationally by Dick Clark.
I loved the show and still enjoy many of the Dick Clark productions.
