[Intro]
A7 E7 B7 E

[Verse 1]
E                                              A7
Pick a lotta cotton drag a long sack
B7                                           E
Comin\’ cross the field well I see Boss Jack
E                                                         A7
He\’s a-ridin\’ straddle of a single foot roan
B7                             E                                           E7
When you know that horse you\’ll leave him alone
E7                                           A7
That old roan\’s got green in his eyes
B7                             E                             E7
Mean as the devil and twice as wise
E7                                           A7
Fire in his nose and a bow in his back
B7                                                         E
Can\’t nobody ride him but Boss Jack

[Chorus]
A7                                           E7
C\’mon children bend your back
B7                                  E7
Work a little faster fill your sack
A7                                                         E
Then you hitch up the wagon take it to the gin
B7
Finish pickin\’ before the winter sets in

[Interlude]
A7 E7 B7 E

[Verse 2]
E                             E7                             A7
Now here a while back when the crop was laid by
B7                                           E
Remember who took us on a big fish fry
E7                                           A7
Caught a heap of catfish, goggle-eye, and carp
B7                                                         E
Danced and sung to the guitar and harp
E                             E7                             A7
Well someday ol\’ Boss Jack\’s gonna set us all free
B7                                           E
Gabriel\’s gonna blow for you and me
E7                                           A7
Angel\’s gonna bring that chariot from above
B7                                                         E
Flappin\’ their wings like a turtledove

[Chorus]
A7                             E7
C\’mon children bend your back
B7                             E7
Work a little faster fill your sack
A7                                           E
Then you hitch up the wagon take it to the gin
B7
Finish pickin\’ before the winter sets in

[Outro]
A7 E7 B7 E
