Original song: By John Lee Hooker
Its just a 12 Bar progression

E----------------     X4------|     The lead parts are played by a
B-----------------------------|            heavily amplified harmonica, you
G-----------------------------|            can just add blues licks between
D-7-7-2-2-5-5-7-5-------------|            each bar to give the song more feeling
A-7-7-2-2-5-5-7-5-------------|            The song is played half a step down, but its
E-5-5-0-0-3-3-5-3-------------|            also alright to play standard tuning or in any
                             other key.
