OK. solve this:
The motion picture soundtrack, yet alone the motion picture of EVITA, is terrible. Hollywood, as usual, took a wondeful piece of work (the hit musical EVITA) and butchered it to be their way. Patti LuPone is a far better Eva than Madonna, and at least you can understand Mandy Patinkin, unlike Antonio Banderos. Also, Hollywood turned the orchestrations into modern rock 'n' roll junk, when the 1979 Premiere American Recording is the way EVITA should be. So don't waste your money on the movie sountrack, and buy the Premiere American Recording instead
Answer:
Negative
