This is Weekend Sex Change off of Calculating Infinity by The Dillinger Escape Plan

It's a very simple song that I figured out by ear, the main part goes like this:

E|----------|
B|-----8----|
G|----9-9---|
D|---10--10-|
A|--0-----0-|
E|-0--------|

Closer to the end of the song it starts getting a little distorted and it goes like this:

E|--------------------------|
B|-8---8--7---8--8-9--7--8--|
G|-9---9--8---9--9-10-8--9--|
D|-10--10-9---10-1011-9--10-|
A|--------------------------|
E|--------------------------|
