What songs underscore the bows and exit music for this show? It's been years since I've seen it onstage, and I don't really remember.

It's "Guys and Dolls" that is playing during the bows. As far as exit music, our show didn't have any. Not sure if that was just our director's decision or what. If there is exit music, my guess is that it's probably more of "Guys and Dolls."

In ours the music for the bows is the Havana music for some bizarre reason.

Well our curtain are like this:

Male Chorus ~ Luck Be A Lady
Female Chorus ~ Fugue For Tinhorns (Yeah they didn't know what song to use, and ours is repeated in the show with Chorus)
Salvation Army ~ Follow The Fold
Drunk, Waiter then Joey, Mimi then Brannigan, Agatha then Harry, Big Jule ~ Guys and Dolls
Dancers ~ Bushel and a Peck
(The last two might be the other way around, I can't remember!)
Salvation Army Soloists then General Cartwright, Arvide (well, Abigail in ours) ~ I've Been Changed (this awesome gospelly type song we put in the show for our group of about 20 Salvos so they had more to do!)
Nicely-Nicely, Benny, Rusty ~ Sit Down You're Rockin' The Boat
Adelaide ~ Adelaide's Lament
Nathan ~ The Oldest Established
Sky and Sarah ~ I've Never Been In Love Before (Just Sky had it originally and Sarah had 'I'll know' then it was changed to Bell and then she was given this to share)
Then the Ensemble ~ Guys and Dolls

Exit Music ~ Guys and Dolls

Yeah the curtain calls are like 10 minutes long!
