I tried to find this film which I watched back in the day. It's not even out on DVD, I find that pretty amazing. Even if perhaps it was not the next Footloose, it still had rock, Joan Jett, and Mike Fox, so you'd think it would be worth it to dump it on DVD.
Joan was only about 18 at the time. [Oops, 28/29, sorry.] I think she looked/looks better later. Probably a matter of learning to tweak your looks right and projecting It. (Well, who looked good in the eighties anyway?)
Bert told me:
Apparently because W-B won't release the rights to one (!!) song in a key scene (a slow dance, if that rings a bell for you).
Dang, that's stupid.
I'm reminded: I have WKRP Cincenatti on DVD. To release it, they had to replace a big number of the songs they played, otherwise it'd have cost a fortune to release it.
It's a strange thing that it is so incredibly expensive to buy most music for a movie. Sure, it's a major use, but at the same time, it can be very valuable PR. Many songs have had major revivals because they were used in a popular movie.
