Capo 2

[Verse 1]

C                                              Am
It's a mighty hard row that my poor hands have hoed
C                                      Am
My poor feet have traveled a hot dusty road
C                                     Am
Out of your Dust Bowl and Westward we rolled
C                                                 Am
And your deserts were hot and your mountains were cold


[Verse 2] 

C                                   Am
California, Arizona, I harvest your crops
C                                          Am
Well its North up to Oregon to gather your hops
C                                                        Am
Dig the beets from your ground, cut the grapes from your vine
C                                         Am
To set on your table your light sparkling wine


[Verse 3a] - On Minnesota Tapes

C                                        Am
I worked in your orchards of peaches and prunes
C                                         Am
I slept on the ground in the light of the moon
C                                         Am
Every state in the Union us migrants have been
                   C                             Am
We'll work in this fight and we'll fight till we win

[Verse 3b] - On Gaslight Recording

C                                         Am
I slept on the ground in the light of the moon
C                                        Am
I worked in your orchards of peaches and prunes
C                                         Am
Wherever your crops are, I'll lend you my hand
C                                       Am
I'll ramble all over your green growing land


[Verse 4]

C                                        Am
Green pastures of plenty from dry desert ground
C                                              Am
From the Grand Coulee Dam where the waters run down
C                                         Am
Every state in the Union us migrants have been
C                                        Am
We come with the dust and we go with the wind


[Verse 5]

C                                      Am
It's always we rambled, that river and I
C                                               Am
All along your green valley, I will work till I die
C                                        Am
This land I'll defend with my life if need be
         C                                 Am
Cause my pastures of plenty must always be free
