I knew it as down in the valley where she followed me
The verses I remember started off with green - she was a virgin queen
brown - I had her panties down
pink - she made my fingers stink
blue - I fucked her through and through
grey - I had ten quid to pay
fawn - one little bastard born
red - one little bastard dead
check - I wrung her fucking neck

Not necessarily in that order and there may have been some other verses
