Don’t watch this movie unless you’re prepared to Rock Rock Rock! Considered an early jukebox musical, it features Chuck Berry, LaVern Baker, The Moonglows, The Flamingos, and Frankie Lymon & The Teenagers - all served up by disc jockey Alan Freed himself. And there’s a plot plot plot! Teen Dori simply must have a dress for the prom but what’s a girl to do when Daddy has cut off her allowance? If you’re able to catch your breath among the musical performances, heartache, labyrinthine financial machinations, and extortion, keep your eyes peeled for a young Valerie Harper.
