This was shown to me by my friend Ryan.. I don't claim any credits for this at all. This is all he taught me for the song, i know its not the WHOLE theme, but there is only the small end part missing.

Standard EBGDAE tuning.

A = 10th fret
B = 11th fret

1st part:
E: |-----------------------|
B: |-----------------------|
G: |-----------------------|
D: |-----------------------|
A: |-2(x5)-6(x5)-7(x5)-A-9-|
E: |-0(x5)-4(x5)-5(x5)-8-7-|

2nd part:
|-----------------------|
|-----------------------|
|-----------------------|
|-----------------------|
|-2(x5)-6(x5)-7-6-4-6-4-|
|-0(x5)-4(x5)-5-4-2-4-2-|

**REPEAT 1ST PART (this = 3rd part)
