Playing with 4 Part Harmony

I've never tried this before, but I've always wanted to write some 4 part vocal jazz harmony. This is a test that I may use in the show I'm currently working on. It was challenging and fun due to the chromatic parts. The Alto part is horrible, but it all works together! I couldn't really sing the parts because 1) one is too high, and 2) I'm doing this at 3 AM and I don't want to bug my neighbors.
