for the ones who know this song, here's the tab

intro is played like this:

D----6------------------
A------------8--------6-----6-5--
E-4-----6-6----6--4-4---4-5-----5-4-

every second time you play this, you must drop the last five notes : 
and play these two notes :

A----6-*take a rest here-------------
E-5-----------------

that's all, just play some variations during the song by playing only 
the 'bassline'
