fun,fun..fun,, this is my last offer,,It looks like (maybe) he's playing:
Em(with an A on top): 022455 (where he hammers the 3rd string from the 2nd fret to the 4th fret: 022255 to 022455)
G: 3x0033
D(with an E on top): xx0230
C(with a D on the 2nd string): x3x033 (or maybe it's x32033)
I think he starts of with a hammer on the 5th string from A to B(he makes on the same time the barre finger) then he follows with a hammer on from A to B third string put his pinky on the E second string and strums/pick it down---then he goes to a G chord wit a added D second string..
Edit;; second thought on the beginning and later on in the song,, he hammers from A to B 5 string and lay down his Barre finger and pinky on the E second string and strums down on the 4 top strings and hammers his A to B 3 string,, I would call the chord a Bsus4,,(lets see if he makes a B furter on the neck,,I did see a A...
something like this.....
EDIT: CHORDS furter on the neck ......
