SIX-PACK TO GO
(Hank Thompson - Johnny Lowe - Dick Hart)
« © '59 Hall-Clement Publications » C F C
Hey, Mr. Bartender! Please don't be so slow.
C A7 D7 G
I've got time for one more round and a six-pack to go.
C F C
Tomorrow morning is Sunday. I'm gonna be feeling low,
A7 D7 G C C7
So please, Mr. Bartender, I want a six-pack to go.
Chorus:
F f#dim C C7
I've been drinking all night long, painting up the town.
F f#dim C Ab7 G7
I've done spent my whole paycheck just a-honky-tonkin' round,
C F C
And I don't have enough to pay my rent. I ain't a-gonna worry, though,
A7 D7 G C
'Cause I've got time for one more round and a six-pack to go.
