I'm Sure This Is Right. I'v Played This With My Friends Dozens Of Times. Could Be Drop D 
But Sounds Better In Standard.

----------|------------|   This can be played by bass and the two guitars
----------|------------|   but sounds better played by just bass. Speed up

This is how it is played but it sounds better if the notes are held fot the same duration like so:
                      -----------------|
                      -----------------|X4
                      ------3~~~1~-----|
                      -5~~~~------6~---|

Either way, end on: ---|
                    ---|
                    ---|
                    -5-|
