This is my first tab, but I think I got it right.

Key: F

Main riff: listen to the song to get the rythm right

e ---------------------------------------------|
H ---------------------------------------------|
G -------5/7-----------------------------------|
D -------------8-----5-------------------------|
A -------------------------8--5--8--5---8----5-|
E ---------------------------------------------|

Then after that you just play with this (actually it's pretty good and easy song to 
practice scales and impro):

e ----5---6-------8----6----5-|
H ----5---6-------8----6----5-|


And then chords for the verse are Gm7 and C7. That's it!

Cheers!
