most of the song can be played off this riff

G—————————7—9——————————————————————————————————————————
D—————5h6——————————————————————————————————————————————
A——5h7————————————5h7p5————————————————————————————————
E——————————————5h7——————7——5—5—3———————————————————————

some versions theres a slide in there i like the slide kinda spices things up

A——5h7————————————5h7p5————————————————————————————————
E——————————————5h7——————7——5—5—3/53———————————————————

the solo is based around that riff with alot more notes thrown in great song 
this is just a starting point use your brains and improvise some with the solo


im glad to see others posting some mule tabs
