This song is in the key of C.  To make it sound like the record, you need to tune to drop D, 
then tune everything down a full step.
Please don't comment that my chord chart is completely wrong when you didn't read the above
 notice.

It should look like this:

E tuned to D
B tuned to A
G tuned to F
D tuned to C
A tuned to G
E tuned to C

*Note* If you prefer, you can play the F/C in place of the Csus4 throughout the song.  
I think the open note sounds better, and is what is being played on the album.
Try both and you'll agree it's very hard to tell.
The F/C looks like this:

D-1
A-1
F-2
C-3
G-3
C-X
