Oops, did we forget "Grease" and "Saturday Night Fever"!
OMG! How did we miss those?
I was on the Academy Awards site when I was researching the "Scifi Symphony" article, and I noticed that up until 1961 there was a whole separate section for musicals' scores as opposed to drama or comedy. Then it switched to original score as opposed to adaptation (with about a 4-5 year switch back in the late 60's with the renewed popularity of musicals thanks to Barbara!) and back again to original/adaptation.
Just thought it was interesting.
