I am pretty sure this is right. I watched him play it on his DVD, and I went from there.
The Strumming Pattern is:
d--3-3-3-3-3-3
A--3-3-3-3-3-3
F--0-0-0-0-0-0
C--0-0-0-0-0-0
G--2-2-2-2-2-2
D--3-3-3-3-3-3
D D U U D U
Verse:
G - F - C/G
At the end of the C/G Chord he sometimes adds:
d-------------------|
A-------------------|
F------0-0h2-0------|
C--0h2---------2p0--|
G-------------------|
D-------------------|
The Chorus is:
[ Tab from: http://www.guitaretab.com/k/keller-williams/64156.html ]
d-------------------------------------------|
A-------------------------------------------|
F-------------------------------------------|
C----------------------5--4-----4--4h5p4p0--|
G----4--5--4--4h5p4p0--------5--------------|
D--5----------------------------------------|
People watching In the street.......
d---------------| d---------------|
A---------------| A---------------|
F---------------| 3 Times F---------------|
C------0h3p2p0--| C---------------|
G--0h3----------| G--3s5--3s5--3--|
D---------------| D---------------|
At the end, he plays the same above, and then slaps the 12th fret harmonics.
This is as much I got from the DVD. Feel free to email with any corrections.
