Thanks guys, great suggestions.

I'd actually remembered the Lovett/Colvin duet last night and looked it out -- amazing the number of times I've gone back to that Asleep At The Wheel disk, after really quite a number of years. It also has one of the weirdest duets, if that's what you call it, that I've heard, albeit quite a nice one -- that would be Willie Nelson piece with Manhattan Transfer, forget the name.

I'll keep looking, too.
