This is a good song, sorry but I couldn't find lyrics anywhere and I'm too lazy to type 
out
It sounds best if you play it nice and sloppy
This sounds correct:

Verse:

E|-----------------------------|
B|-----------------------------|
G|-----------------------------|
D|-----------------------------|
A|-----------5p3---0-----------|
D|---0---0-------------5---3---| X3
After the 3rd time you play this:
E|-----------------------------------|
B|-----------------------------------|
G|-----------------------------------|
D|---0---3---5---5---5---5---5---3---|
A|---0---3---5---5---5---5---5---3---|
D|---0---3---5---5---5---5---5---3---|
This is the same as you play in the chorus

Chorus:
E|-----------------------------------|
B|-----------------------------------|
G|-----------------------------------|
D|---0---3---5---5---5---5---5---3---|
A|---0---3---5---5---5---5---5---3---|
D|---0---3---5---5---5---5---5---3---|

                Texas, its our thang
(Play the 6th string loudest)
