E|---------------------------------------------------------------------------|
B|---------------------------------------------------------------------------|
G|---------------------------------------------------------------------------|
D|--------------------------------7---6---4----------------------------------|
A|-4--------4--------4--4----------------------------------------------------|
E|-----2---------2-----------2-----------------------------------------------|



[before the band stops playing and its only Stu singing you finish off the main riff with this:]

E|-----------------------------------------------|
B|--6-----6-----6--6-----9--8--6h8p6h8p6h8-------|
G|-----------------------------------------------| (x2)
D|-----------------------------------------------|
A|-----4-----4--------4--------------------------|
E|-----------------------------------------------|

E|------------------------------------------------------------------------|

E|2--2--2--2--2--2--2-----------4--4--4--4--4--4-----------5--5--5--5--5--5---------7--7--7--7--7--7---------|


You repeat this twice and on the second repeat finish it off with this part from earlier:

D|---------------------------------------------------------------------------|
A|---------------------------------------------------------------------------|
E|0s7--7--7--7--0--2h5--5--5--5--2--0--2-------------------------------------|
