This dream would be better set to music

The only part of the dream I remember was argueing with my Dad about the, wow this is hard to explain, we were looking at all the different types of recordings of Les Miz, and I was trying to clear up their chronology? We have the DVD of a 10th anniversary special, which combined the best of the original Broadway and London cast aka the "Dream Cast". When I was growing up we listened to a cassette recording of the main songs of this performance. The CD we now have is a more recent recording (albeit still 10 years old I think) that is made up of contemporary cast members from all over the world. I dunno what you call that kind of clarification. But my Dad wasn't interested and he was making me mad by not listening to me.
