This is what actually mike plays this song, there's a ,of bass tabs for this but all of them is wrong... 
BTW I used the bass track for this so It's 90-100% right ;)
It's a little hard for  beginners but if you can do octaves in bass then your good to Go! 

Bass starts at 00:37 (think I'm cracking up)
