Who were the African-American teens who persisted until they got on American Bandstand in October 1957?

Answer 1

None. No such thing happened, so the answer is in three parts. 1. Hairspray (the movie) is not a documentary. It is not even a Docu-Drama. It is a fictional performance that only vaguely resembles some things from the 1950's. 2. American Bandstand was not limited to "only white" dancers. 3. Any racist similarities between Hairspray (the movie) and the real events of the 1950's in the U.S. are lifted from events regarding the Buddy Deane Show. The Buddy Deane show was another 'dance-to-the-hits' show broadcast from Baltimore. That is the show that did not mingle Black and white dancers on the same dance floor. That is the show that had 'all-black' Fridays (taking into account that the show was a Daily show). When the Buddy Deane Show was pressured to integrate white and black dancers (like American Bandstand had already been doing), the show's powers-that-be refused and the show was subsequently cancelled.
