This is a rough outline for the intro, I didn't have my guitar with me when I did this, 
so I think the rhythm is a bit out.

E|------------------------------------------------------------|
A|------------------------------------------------------------|
D|-5-5-555-5-5-5-5-5------------------------------------------|
G|-7-7-777-7-7-7-7-7------5-5-5-5-5-6-6-6-6-------------------|
B|------------------10-10-7-7-7-7-7-8-8-8-8-10-10-10/2-2-2-2h3|

D|------------------------5-5-5-5-5-5-5|
G|-1-1-111----------------7-7-7-7-7-7-7|
B|-3-3-333-10-10-10-10-10--------------|

Repeat as appropriate, that's roughly it.
