loheroh Thanks for posting the link and the starting point. I just saw it and listened to the song and I'm going to work on it this weekend for you. I'm gonna try to get it done by Sunday night.

Submitted it as a chords because there's only one instance of lead playing at 1:14 when he hammers onto a Asus4. 

Working only off of a pair of ears and hands I don't think anyone could've done you much better. 

If you had someone who knew more about theory they would accurately derive the chorus chords from the vocal melody and piano harmony.
