For seven years it was a hot spot of teenage American pop culture.
From 1957 until 1964, Dick Clark hosted American Bandstand at the West Philadelphia studios of WFIL-TV, where thousands of teens dreamed of appearing on the hit show.
But few actually got the chance to dance inside the nondescript building in the shadow of the Market-Frankford El at 46th and Market Streets.
If you were one of those teens who yearned for your Bandstand moment, here's your chance.
On Saturday between noon and 3 p.m. the current owners will open the former Studio B for three hours of tours, reminiscing, and perhaps, one last Twist on the dance floor.
