hey this is a great song and extremely easy to play. i'm surprised someone hasnt put it 
here already.

e|-4-4-4-4-4--4-4-4----------------------------------------|
b|-7-7-7-7-7--4-4-4----------------------------------------|
g|-6-6-6-6-6--6-6-6----------------------------------------|
d|-4-4-4-4-4--6-6-6----------------------------------------|
a|-4-4-4-4-4--4-4-4----------------------------------------|
E|---------------------------------------------------------|

those same chords over and over. if you know the song you know the rhythm. it's easy.
