It's tuned down a full step, i think.

If it?s too hard to stretch your fingers in part II, you can play:

Rhythm during lead:

Verse: play the first part 1 time and the second part 3 times

|-----------------------------|----------------------55---------|
|-----------------------------|------33------66------55------33-|
|-----------------------------|------44------77------55------44-|
|-22----0022----0022----0022--|-0022----0022----0022----0022----|
|-----------------------------|---------------------------------|
|-----------------------------|---------------------------------|

then play the intro thing again and then the second part of the verse with no lyrics
then start the verse again

The chorus is just the second part of the intro

Bridge:
|---------------------------------|
|---------------------------------|
|---------------------------------|
|-77--7-7-55--5-5-44--4-4-55--5-5-|
|-55--5-5-33--3-3-22--2-2-33--3-3-|
|---------------------------------|

then, you strum the chords for the second half of the bridge

thats my best guess
