Mamma Mia! There's certainly a trend for creating musicals using music from popular bands (e.g. "We Will Rock You" etc). I'm not sure this is relevant to my research, since the songs weren't written specifically for a play/film, instead a story was put around the music. Though, I could be wrong, I'm not too sure of the layout of it, since I haven't seen it. Perhaps I could ask someone who has seen it already.
