Well, since I usually get cast in supporting character roles, this is kind of a moot post....but I'll play along....
I would like to be Nicely-Nicely in Guys and Dolls....I sorta look like a black Stubby Kaye anyway....well, kinda...
Others would be:
Joe in Merrily
Roscoe in Follies
hmmm....
Beadle Bamford or Pirelli or Toby in Sweeney
Domina, Hysterium or Erroneous in Forum (already played Lycus)
Zoltan Karpathy would be fun.....(but I think the Bartender has funnier lines)
Nachum the Beggar in Fiddler
Cheers,
The Balladeer
