Dean,

I just listened to this. You da MAN! You are without a doubt the most talented (in multiple directions) jazz musician I've ever known! You strike me as the kind of guy who could take any chord pattern and come up with countless arrangements and never duplicate any of them!

What you are asking for here, however, is a bit different than the instrumental masterpieces you are so good at creating. Here's my unqualified opinion, feel free to disagree with it.

I think if you strip this down to bare bones so the singer has some room to play with it, you'll get more takers. You can always embellish the empty spots later after you hear what the vocalist came up with.

As I listened with an ear of how to sing along, my gut feeling was that it almost works as an instrumental.. there's enough going on already that a singer would be dealing with space constraints.. and that doesn't lend itself to playful experimentation.

By starting with a bare-bones progression, any vocalist would have maximum leeway to do whatever they want... and then your irrefutable genius level skills at arranging can take it from there.
