The original (or at least the original I have) is in the key of F Major
Intro
Back-up vocals sing the first line in the song in the following manner:
[F] [Bb] [C] [F]
Take these chains from my heart and set me free
(the first F chord in that string of four is for the pick-up note where the girls sing a C note)
Verse 1
[F] [C]
Take these chains from my heart and set me free
[C7] [F]
You've grown cold and no longer care for me
[F7] [Bb] [G7]
All my faith in you is gone, but the heartaches linger on
[C] [C7] [F]
Take these chains from my heart and set me free
Verse 2
[F] [C]
Take these tears from my eyes and let me see
[C7] [F]
Just a spark of the love that used to be
[F7] [Bb] [G7]
If you love somebody new, let me find a new love too
[C] [C7] [F]
Take these chains from my heart and set me free
Verse 3
[F] [C]
Give my heart just a word of sympathy
[C7] [F]
Be as fair to my heart as you can be
[F7] [Bb] [G7]
Then if you no longer care for the love that's beating there
[C] [C7] [F]
Take these chains from my heart and set me free
