Basically just these three chords in the back all the way trough.
Listen to the song to get the strumming right.

B|---x--------5--------0---|
G|---2--------4--------1---|

This is the picking part in the intro and ending.

The song ends with this in the end of the picking part.

Those who are familiar with the version of the song, where the piano
joins in the end, I managed to figure out those parts too.
