The song basically has 6 chords-

0  0  0  0  0  0
0  0  0  7  8  0
6  11 7  0  0  8
7  12 7  7  7  9
7  12 5  5  5  9
5  10 x  x  x  7

The rhythm isn't too hard to figure out.

At the end, I think Dave's using this chord-

0
0
4
5
5
3

He ends it with a minor 7th, but I don't know what that is.

Dave also uses this type of chord (E bar chord with open b and e strings)
on the intro to "Ocean Size"

Also, if anyone has the tab to "Three Days,"  please send it to me...
