INTRO and POST-CHORUS

The intro is G but then he hammers on (and pulls off) on the D and B strings 
(essentially making a C with G bass):

e|--3--3----|
B|--0--h1---|
G|--0--0----|
D|--0--h2---|
A|--x--x----|
E|--3--3----|

So strum a G, then hammer on, strum a few more, then pull off on a strum. Repeat four 
times. Listen to the song for exact timing.
