This is a really easy piece. It is just one recurring tune on the bottom string. 
Normal tuning. Here we go:
G———————————————————————————————————————:
D———————————————————————————————————————:
A———————————————————————————————————————:
E—5—5—5—0—3—3—3—0—8—8—8—0—1—1—1—————————:

Repeat this throughout the song, except the part:" Hate to say I told you 
so" is sung.
Enjoy.
