Two ways to play it. it depends on how the chord progression goes..
CAPO ON 2ND FRET

1e:-----------2---------|
2b:--0--2--4-----4---2--|
3g:---------------------|
4d:---------------------|
5a:---------------------|
6e:---------------------|
and you just keep replaying that... another way is WITHOUT THE CAPO:

1e:--------1--4----1-------------|
2b:-2---4-------------4----------|
3g:------------------------------|
4d:------------------------------|
5a:------------------------------|
6e:------------------------------|
and then replay that.. it all depends on how the chords are played. if theyre played 
capo on 2nd then the first intro is correct.. if there is no capo used to play this song 
obviously the second one is right! enjoyyy :))
