This is my take on Wagon Wheel.
This tab is deceptively simple. The rhythm can get sticky if you don't watch the ones 
and twos (especially with the hammer-ons in the beginning).

I like to finger-pick the verses and strum the chorus

G                     D
Rock me, mama, like a wagon wheel
Em                 C
Rock me, mama, any way you feel
G      D          C
Hey... hey, mama, rock me

That's about it. Have fun with it.
