If you have that Sondheim bari-tenor voice, there's some good stuff from Into The Woods! Also, the Balladeer's bits from Assassins are great, and so are some of the songs the supporting characters sing in Forum. I like "Lovely" the best, and it sounds a bit more traditional, if that's what you're going for. I dunno.
I know it's really written for a tenor, but "Something's Coming" would sound nice with a strong baritone, if it's not too overdone.
...yes, I know, I'm a Sondheim freak.
