This is interpreted from Matt's performance in Nanaimo in 2006.
If you don't quite understand the minor changes I'd suggest looking it up just so
you can hear and see how to do it. I didn't include number of repetitions in
intros and whatnot, this is just a guide.
In the Demo there are alot more hammer ons in the bottom 3 strings (specifically
b) so play around with it until your satisfied.
Tuning: Half Step down
Capo on the third fret

Chords:
C (x32010)
Cmaj9 (020010)
Am (x02210)
G (320013)
Cadd11 (x33010)
G (320033)
Gsus2 (300233)

*Every time Am is played in the verses/intro/outro hammer on the b string*

Intro: C Cmaj7 Am G*
*C lead in* close to the end of each G remove top two fingers and play a string on the 
3rd fret then open, one strum each, just as a lead in back to C. 0*3*0013 00*0*013 the 
stars are around the notes focused on.

Disappear you down this trail of busted years to ride the rails and goodbyes
