The Bed's Too Big Without You

There are basically 2 parts to the song: Tabbed by Malav Trivedi.

This is the main really cool bass line that we all know and love:

G------------------------------|
D------------------------------|
A--7-7-7-7---------------------|
E----------7-7--3-0-0----------|



This is the other bit:



G----------------------------|
D---------5-5----------------|
A----5-7------7-5-7-7--------|
E--7------------------0------|

  
That "other bit" needs to be played really fast. If you practice it enough you'll get the hang of it. It's also kind of hard to play the "other bit" and sing at the same time. 
Again, practice, practice, practice....
