"I'm Gettin' There" - Mose Allison
A wee bit of a reach, but a valid response, none the less. Mose is one of favorite jazz singers and many of his songs can be adapted to jazz guitar (from sax & piano). "Certified Senior Citizen" is my fav, as it's so funny.
I also wanted to comment on Kaleb's quote of Ace Frehley about a Les Paul guitar & a Marshall amp, crank it up to 10 is pretty much a no-brainer. That's EXACTLY what I did to find my voice!
