I was expecting other people to be all over this tab 'cause this song is awesome, 
catchy, and simple. 
But I still don't see any tabs for it. So, I decided to put up the chords. 
It's a simple four-chord progression:

F C Dm Bb

Piece of cake. But here are the lyrics with the chords just in case:

F (133211@1)         C (x32010@1)            Dm (xx0231@1)            BbHearts (x1333x@1)on a string like an older-fashioned phone can
