..and repeat..


from some point (1.13 min), something like this is repeatedly played over 
the piano chords:


  Riff 2:

E|-8--8--10--------------------|--13--13--15s\--------------------|
B|-8--8--10--------------------|--13--13--------------------------|
G|-9--9--10--------------------|--14--14--------------------------|
D|-----------------------------|----------------------------------|
A|-----------------------------|----------------------------------|
E|-----------------------------|----------------------------------|


Towards the end of the song, I think they play this chord (barred G):

E|-3--|
B|-3--|
G|-4--|
D|-5--|
A|-5--|
E|-3--|

over and over. 

Listen to the recording for the strumming pattern on this chord;
I think it shifts the accents from the lower to the higher strings
every now and then.
