Since 2 people requested tabs for this on my youtube video I decided to post them up 
here since all the other tabs of this song are not so great.

People have tabbed many different versions of the intro but I am positive this one is 
right since I watched a video lesson from My Chemical Romance themselves watch the video 
here http://www.youtube.com/watch?v=qFMBzQe7unQ

Watch my bass cover of this song!
