this is what the riff part is i believe E------------------------------------------------------------------| B------------------------------------------------------------------| G---------------------------------------------------------------1--| D---------------1-----------------------------------1-----1--4-----| A------1--2--4-----4--2--1-----------------1--2--4-----4-----------| E---4-----------------------4----------4---------------------------| but i find that the song is easier to play with a capo on 1, so that nice chords can be (Em, C, G etc) and so this riff look like this relative to the capo: E------------------------------------------------------------------| B------------------------------------------------------------------| G---------------------------------------------------------------0--| D---------------0-----------------------------------0-----0--3-----| A------0--1--3-----3--1--0-----------------0--1--3-----3-----------| E---3-----------------------3----------3---------------------------|
