Yes, "Some People" is another film of the type I'm thinking of. I can't actually remember seeing it, but I probably did. The theme song was recorded by Valerie Mountain, but there were a couple of other versions from Carole Deene (mentioned above in this thread) and Jet Harris, both IMO better than the 'official' one.

Most of these films had pretty dire plots about youth clubs, dastardly property developers hoping to bulldoze them, and teenagers forming bands to raise money to buy the site and save the youth club, so we had the excuse for the gigs to be filmed (OK that was more or less the plot of the Young Ones, but from what I remember, most of the other films had similar storylines).

(I can't remember Aneke Wills - what was her name in Dr Who? I can remember most of the other girls though :D)
