I first saw this show in 1986 and it became one of my favorite all time television shows. The Singing and dancing was great - especially enjoyed how they reworked the 50's and 60's tunes to reflect the actions in each episode. The girls were cute - especially important to a teenage boy (had a major crush on Bridget Michele (Diane) and Kimiko Gelman (Rose).
Unfortunately, I never did get to see all 21 episodes of the show, and only was able to record four episodes on VHS in 1987 (which I have since transferred to DVD and still enjoy).
Sad the show did not even last one season, but it is truly a nostalgic gem for both the 1980's and 1960's.
