Thanks guys for the great advice. A bass player wouldn't be my first choice for a dou but it's not my gig. But the more I think about it, I think it could work well. I'm preparing by working on 2 handed piano comping and coming up with my OWN intros and endinds. Also I think he'd be open to me covering the bass on some of the funky stuff that he sings lead on. Should be fun because we're covering all sorts of styles- Latin, C&W,R&B, and the old standards too.
