KJisgroovy: Thank you for bringin up the subject of "rediscovering" CDs. It happens to me a lot, I guess your current mood and expectations may affect your initial impression of a cast album you might later pick up again and love. As for your questions, the US Martin Guerre is called something like "U.S. Tour Cast Recording" or something. I don't have it with me now, so I can't give you more details, but it's basically the same music as the London version but with different lyrics and song order. I liked the show in London but this US CD did nothing for me. I guess they recorded the show because they wanted to have the CD ready for sale during the big Broadway opening weeks . . . which as we know, never happened.
Some Like It Hot is the London version of "Sugar". It starred Tommy Steele and is inferior to "Sugar" which I think is just an OK show to begin with. Tony Curtis did a recent tour of this latter version in the US but I think it flopped.
I did not hate Patti in Evita, just in Sunset. It's just that, as someone wisely pointed out, Mandy Patinkin and La Lupone are cursed with that love it or hate it thing. I loved her in Eva, hated her in Sunset. I generally hate Mandy Patinkin, though! (not that anyone asked).
The meat is always leaner on somebody else's dinner plate!
