Learn to Play Guitar

I don't know how I have managed to get through life without learning how to play the guitar. My little brother, Billy Bones, is an amazing musician. He can pick up an instrument he's never seen before, & learn how to play it inside of an hour. He's in a ton of bands, has his own record label, & owns a company by the name of Sparrow Guitars based in Vancouver, BC. My mother ensured that I played my scales, & I grudgingly practiced the piano for many a painful lesson, but I just never had the ear for music that most of my family has. I've had a few acoustics (all of which ended up in some pawn shop or another) but never really figured it all out. Certainly, I can strum a few chords, but it just isn't enough. I want to rock and roll, & maybe even fit into some great leather pants, a la Joan Jett, although I'd settle for playing Guitar Hero in my underwear...
