What career(s) would you like to be added to TS4?

I want to have a sim be a singer but not a rock star type. I'd rather they sing torch songs with a back up band. I'd like it to be a semi active career where you can actually set up places where they can sing for crowds. Better yet if we have couple dancing in game and they can sing at events and other sims can dance.
Then I'd like a band that can play at events also especially if we could get ballroom dances.
