This was the only screen appearance of Danny and the Juniors, who performed "At The Hop", and The Royal Teens (with Bob Gaudio), who performed "Short Shorts". They were two big rock groups of the late 1950s.
Film debut of Charles Nelson Reilly. He had to introduce a musical act and couldn't get his one line right. He was so funny trying so hard to get the take done that people from all over the lot were arriving to see him flubbing his dialogue. It took over 60 takes to finally get the shot.
