G--------------------------------|
D------5-------------5-----------|
A--------2-3-4-5-------2-3-4-5---|
E--3--------------3--------------|

and so on.

Then for the bluesy breakdown/rhythm just play a normal blues shuffle

Play the chords
e-----------------------------------------------------------|
B-----------------------------------------------------------|
G-----------------------------------------------------------|
D-----------------------5-5-7-5-------------7-7-9-7---------|
A--5-5-7-5---5-5-7-5---3-3-3-3--5-5-7-5----5-5-5-5----------| then back to G and so on
E--3-3-3-3---3-3-3-3-------------3-3-3-3--------------------|

     G                                     C              G                   D

Thats just an idea....
the blues rhythm might not be correct but the main riff is correct.
