Mary Had A Little Lamb - Stevie Ray Vaughan
Stevie Ray Vaughan is an all time giant of blues guitar and this is one of my favorite tunes of his, and it's quite playable, there's nothing super technically complicated going on so it's a great one for intermediate players to get under their fingers. It's also a great jamming tune if you play in a band or go to a jam session.
It's an 8 Bar Blues form in E, which starts on an A Chord! A A E E B A E E
The solo is awesome too and I'd highly recommend you having a go at transcribing it, but there's a lesson coming next week for it too :)
