This is one of the coolest bass songs I've ever heard.  Almost everyone knows it, and it's so simply i was suprised i couldn't find an actual copy.  It is the same pattern over and over through out the whole song.  I hate when people say " this is 100% correct" when it really isn't.  If u listen to the song, this is what u hear the bassist playing.  Enjoy.

You can play the open strings instead of 5 on the a and d strings..but this is the simplest way i've found so far. This is my first tab.  Wo hoo
