I didn't know other instrumentalists played Jazz!! Kidding of course, I love Pete Fountain - excellent dixieland jazz clarinet player. Uses very tasteful licks. Played a lot with Al Hirt - who's no slouch either. As far as vocalists... when learning a new tune I always take a listen to how Ella Fitzgerald sings it (shes pretty much sang and recorded all the standards). I get good ideas...love how she does Misty.
