A Night in Tunisia is one of The Manhattan Transfer's most popular songs of all time. An audience pleaser for sure and a good challenge for your vocal jazz ensemble. If you don’t have a singer who can sing the challenging, but fun bass part, you can give the bass singer’s part to your bass player to play and then the singers can sing the SATB parts. Also, this arrangement can be performed SATB, using a rhythm section of piano/bass/drums.
