The Henningsens have been playing this one live 
(https://www.youtube.com/watch?v=A7SyBQOpnLY) so I decided to tab it and upload it.
The version without a capo ("original") is played with the chords A, F#m, D, E, Bm and 
G. I tabbed it without a capo, but I think this is easier for beginners. Click transpose 
+2 if you prefer to play the song without a capo.
