I've got the records for the concept album and original London (but since I don't have a record player anymore, I haven't listened to them in a long time), but I thought the Che in London (David Essex?) was particularly good.
Patti is great in the OBC, but I don't like the sound of Mandy Patinkin's voice (although he does sing well).
I saw the London revival several months after it opened, and I thought Elena Roger had mellowed and her accent diminished, making her performance better and less harsh than on the recording. Matt Rawle's accent seemed to veer wildly (British, American, Spanish/latin), although his performance was decent. I'm sorry that production didn't last long or make it to Broadway, as I thought it was terrific and would have liked to see it again.
I amost never listen to the movie soundtrack, although Madonna's "You Must Love Me" is OK, as I recall. (Elena Roger does that song well, too.)
Aside: What happened to "The Lady's Got Potential" in the OBC? Did they cut that song? I like that song.
