Alabama - High Cotton Chords

*****************************************************************************
This is my first posting, but I'm pretty sure it's close if not right on to the 
original recording by Alabama (according to what I can hear anyway!).
*****************************************************************************
Chord diagram shows something different than I'm doing:

C7 I'm using = standard C + pinkie on 3rd fret 3rd string

Song Title:  HIGH COTTON


[F] We didn't know the times were lean
[Bb] Round our home the grass was green
It [F] didn't seem like things were all that [C7] bad
I [F] bet we walked a thousand miles
[Bb] Chopin' cotton and pushin' plows
And [F] learnin' how to [C7] give it all we [F] had.

[F] As life went on and years went by
[Bb] I saw the light in daddy's eyes
And [F]  felt the love in mama's [C7] hands
They [F] kept us warm and kept us fed
[Bb] Taught us how to look ahead
Now [F] lookin' back, [C7] I [F] understand.

Refrain 1:

We were Walkin' in [F] High Cotton
Old times [Bb] there are not forgotten
Those [F] fertile fields are never far a-[C7] way
We were Walkin' in [F] High Cotton
Old times [Bb] there are not forgotten
Leavin' [F] home was the hardest [C7] thing we ever [F] faced.

When [F] Sunday morning rolled around
[Bb] We dressed up in hand-me downs
Just [F] in time, together with the [C7] church
Sometimes [F] I think how long it's been
[Bb] And how it impressed me then
It [F] was the only day [C7] my daddy wouldn't [F] work.

REPEAT Refrain 1

(Change to key of G:)
Refrain 2:

[F] We were Walkin' in [G] High Cotton
Old times [C] there are not forgotten
Those [G] fertile fields are never far a-[D7] way
[P] We were Walkin' in [G] High Cotton
Old times [C] there are not forgotten
Leavin' [G] home was the hardest [D7] thing we ever [G] faced.

REPEAT Refrain 2

We Were Walkin' In High Cotton.
