I figured I'd try to tab this one since there wasn't a tab for the introduction on UG.

Here's my try at the intro:

e|--------------------------5----------------------|
B|-2--4h5--4--5h7--5--------5----------------------|
G|-2-------4-------6--------6----------------------|
D|-2-------4-------6--------7----------------------|
A|-x-------x-------x--------7----------------------|
E|-2-------4-------6--------5----------------------|

The rest of the song:

Chords:

NOTE: You'll notice if you listen to the recording that, the first time David plays a 
chord, he focuses on the bass note(s). The rest of the times he will play more of the 
higher notes. Keep this in mind when you're picking this song.

Another NOTE: During the verse, it sounds like, instead of playing the top two strings 
of the B chord at the 7th fret for the verse, he mutes the B string and plays an open E 
string. He also sometimes does this same open string thing for the A chord of the verse.
