My first tab, so be nice OK?

Beginning:
e|---------------------------------------------------------------|
B|---------------------------------------------------------------|
G|----------0------------------------0---------------------------|
D|-00-22-33----33-22-00-----00-22-33----33-22-00-----------------|
A|-----------------------3-----------------------3---------------|
E|---------------------------------------------------------------|
Play twice.

Now up an octave:
e|----------3-----------------------3----------------------------|
B|-33-55-66----66-55-33----33-55-66----66-55-33------------------|
G|----------------------5-----------------------5----------------|
D|---------------------------------------------------------------|
A|---------------------------------------------------------------|
E|---------------------------------------------------------------|
Play twice.

Now the exciting bit (listen to the song for the timing, but it's pretty simple):
e|---------------------------------------------------------------|
B|---------------------------------------------------------------|
G|-----2-3---11-2--------2-3---11-2--------2-3---44-3------------|
D|-0-3-----0---------0-3-----0---------0-3-----0-----------------|
A|---------------------------------------------------------------|
E|---------------------------------------------------------------|

e|---------------------------------------------------------------|
B|---------------------------------------------------------------|
G|-----2-3---00-1------------------------------------------------|
D|-0-3-----0-----------------------------------------------------|
A|---------------------------------------------------------------|
E|---------------------------------------------------------------|

The build up (you'll need to listen for the timing again):
e|---------------------------------------------------------------|
B|---------------------------------------------------------------|
G|---------------------------------------------------------------|
D|-00000000000-333333333-002-33332-002-33332-002-333320----------|
A|---------------------------------------------------------------|
E|---------------------------------------------------------------|

Epic:
e|---------------------------------------------------------------|
B|---------------------------------------------------------------|
G|---------------------------------------------------------------|
D|-0-2-3-0-2-3-5-2-3-5-7-3-2-3-5-2-0-2-3-0-----------------------|
A|---------------------------------------------------------------|
E|---------------------------------------------------------------|
Play twice.

Then:
e|-------10-10-------8-8-------10-10-------10-10-----------------|
B|-10-10-------10-10-----12-12-------11-11-----------------------|
G|---------------------------------------------------------------|
D|---------------------------------------------------------------|
G|---------------------------------------------------------------|
D|---------------------------------------------------------------|

Finally back to the beginning bit:
e|---------------------------------------------------------------|
B|---------------------------------------------------------------|
G|----------0------------------------0---------------------------|
D|-00-22-33----33-22-00-----00-22-33----33-22-00-----------------|
A|-----------------------3-----------------------3---------------|
E|---------------------------------------------------------------|
Play twice.

Now up an octave:
e|----------3-----------------------3----------------------------|
B|-33-55-66----66-55-33----33-55-66----66-55-33------------------|
G|----------------------5-----------------------5-7--------------|
