Yelling isn't gonna help us help you.
The male parts are
The Herald (who sings quite a bit, especially in "Prince is giving a ball")
The Chef and Steward, who sing in one number (optionally, for the director to decide [I think])
I'm not sure who the featured men are. But I would assume they are just soloists as there are quite a bit of solos in the first song. And I'm also going by remembering the version we performed, which I believe is the same one you are referring to.
