I've heard both nonch, and Billy Elliot features Amy's kind of brother-in-law (her boyfriend Kevin's brother) singing the first adult solo in the show. It's so much of a visual show, I doin't really remember the music being outstanding - it was nice, but seeing it performed was even better.
Book Of Mormon would get my Tony Award vote for Best Musical Score - it's incredibly well-done, with outstanding vocals by the male ensemble, plus the supporting actress (Nikki something, I forget) sings a song called Salt Lake City that the ladies were singing in the ladies' room at intermission. Both of the lead guys have terrific songs that I hope translate to cd well.
Most of all the music is terrific and the lyrics are truly clever. It was written by the South Park guys, Trey Parker and Matt Stone, PLUS the writer of the score for Avenue Q, which won the Tony for Best Scoreover Wicked! I would say it's up your alley, nonch!
