There are some good Youtube vids on this using two capos at the same time, but this is 
how I play it. Open to suggestions or modifications.

Hammer on and pull off 2nd fret G string (relative to capo) on all chords. I use a G5 
derivative (3X0033) so that my index finger is free to hammer I and pull off G string.

Capo on 3

Intro
F F Am G

                   F
So Whether music or madness
                  Am
Live by one of the two
             G
By one of the two

                              F
Go on, fill your heart up with gladness
                Am
Not a moment too soon
                 G
Not a moment too soon

(Same pattern pretty much all way through I think. You can google the rest of the lyrics 
of you want)
