I've listened to it many times and this is how I play it.
Tuning=Average: EBGDAE
The intro starts like this:
E---------------------------------------------------------------------------|
B-77788-10-8788887788-77788-10-8788887788-77788-10-8788887788---------------|
G-77777--7-7777777777-77777--7-7777777777-77777--7-7777777777---------------|
D-----------------------------------------0-let-ring------------------------|
A-----------------------------------------0-let-ring------------------------|
E---------------------------------------------------------------------------|

E---------------------------------------------------------------------------|
B-77788-10-87888877887--77788-10-8788887788-77788-10-8788887788-------------|
G-77777--7-77777777777--77777--7-7777777777-77777--7-7777777777-------------|
D-0-let-ring------------0--0-----0----------0--0-----0----------------------|
A-0-let ring------------0--0-----0----------0--0-----0----------------------|
E---------------------------------------------------------------------------|
Then the first verse starts.
(Don't mind the spaces in between each number.
There are no pauses in the intro.)
Hope it sonds good for you!
