I couldn't find any bass tabs, so I decided to tab it really fast :P Ps. it's the 
first time I've submitted something here, woah!

The bass comes in at 0:33 or something (if you can't hear it)

.......................the last line.....................................

Pause! I dunno if it's contrabass or something, but some of the notes are a little hard to tab xD

When the bass starts again, just repeat everything like it was first time, EXCEPT the 
last line, play this instead:

G|:-----------|B|---------|---------|---------:|
D|:-5---5-7-8-|R|-7-----8-|-5-----8-|-5-----8-:|
A|:---6-------|E|---6-5---|---5-6---|---5-6---:|
E|:-----------|A|---------|---------|---------:|
              |K|                         

G|-----------|
D|-5---5-7-8-|
A|---6-------|
E|-----------|

The End. Maybe not 100% right, but sounds good enough for me. Try it out!
