The only bass tab floating around for this song seemed a little off so I decided to tab 
it myself.

Main Riff:
G|---------------------------------------------------------------------------|
D|--------6-9----------------6-----------------------------------------------|
A|--7777-------0-0-4--777-------7-444----7-9-6-------------------------------|
E|-------------------------------------7------7-7----------------------------|
Variation:
G|---------------------------------------------------------------------------|
D|--------6-9----------------6-----------------------------------------------|
A|--7777-------0-0-4--777-------7-444----7-9----7-9--------------------------|
E|-------------------------------------7------7------------------------------|
Listen for this part near the end:
G|---------------------------------------------------------------------------|
D|--------------------------6---------6---------6---------6------------------|
A|-------4-7---------4-7--------7-4-------7-4-------7-4-------7-4------------|
E|--000---------000----------------------------------------------------------|
End of part above:
G|---------------------------------------------------------------------------|
D|---------------6---9---7---6-----------------------------------------------|
A|--------6--9--------------------9---7--------------------------------------|
E|----7----------------------------------------------------------------------|


Just listen for the variations, not hard to figure out. Listen to the song to figure out 
when to come in with the ending part. Most of the song is just the main riff. Yeeeeeeeeeeee
