ok, this song is really easy, the entire song is the same chord progression- E, A, B, A.
the E on the 7th fret of the A string, play the A on the 5th fret of the E string, and
the B on the 2nd fret of the B string.

They switch between playing the chords 1 time per measure and 4 times per measure, and
shouldnt be too hard to figure out, and if it is, then you shouldnt be playing guitar.

one more thing, if you want to play the song perfect, then when strumming the chord
only once per measure, strum on the down beat, and when strumming the chord progression 4
per measure, its strummed on the up-beat.
