I've seen some tabs up, but I dont think any of them are spot on. On the verse,
slide the F# to the G(F#/G). Here's my take on the song anyway;

INTRO
e|---10----------
B|------11-------
G|---------12----  (Repeat as many times as you feel neccesary
D|---------------   finish with a stroke of 10 on the e string)
A|---------------
E|---------------
