I do not remember it played with a Dm as far as I can remember from guitar tutor 20 odd years ago it's. C AM F G7 two beats each cord repeated untill (you do not need the Full Bar F cord for reasons of speed as when you get to the) Whiskey O you fit in the F G7 C with a single beat to each chord. Its the same chord sequence as If I Had A Hammer. Its a good one to put your guitar out of tune. Anyway that will work with out having to tie your fingers into too much of a not!
