Here's my idea of the picking for one of my fave songs of all time ;)

E|--------------------------------------------------------------------|

 C                E                Am               F
E|--------------------------------------------------------------------|

G|---0---0---0---0----1---1---1---1----2---2---2---2----2---2---2---2-|

Just play this throughout the song and when you get to the "There are no legible signs" 
and "you're not in the room" parts, play this;


    C       E       F               C       E       F
E|-----------------------------------------------------------|
B|-----------------------------------------------------------|
G|---0---0---1---1---2---2---2---2---0---0---1---1---2---2---|
D|---2---2---2---2---3---3---3---3---2---2---2---2---3---3---|
A|-3---3---2---2---0---0---0---0---3---3---2---2---0---0---0-|
E|-----------------------------------------------------------|

Have fun!!! :)
