This is the first tab i've ever posted, so bear with me if it sucks.

This is the way I think the song Dam is played

(Let ring throughout)
D----------------------------------------------------------------||
A----------------------------------------------------------------||
F------------------------------------------------------3--------o||
C----------7-------------7---------------3--------1--------1----o||
G------5------5-----5--------5-------1------1--------------------||
C--0------------0------0---------0------------1------1-----------||

There, that's the whole song.
