I know this song doesn't really belong on a guitar tab site,
but if you play the song with these chords it sounds very good:
D Em C G
all over again
Could it be more simple

There's also a lead guitar in the song that does sth like this:
D Em C
E------3--0-----|------0--3h5p3---|-----------------
B----2----------|----1------------|-----------------
G--3------------|--0--------------|-----------------
D---------------|-----------------|-----------------
A---------------|-----------------|-----------------
E---------------|-----------------|-----------------
