Hi, Jim. Thanks for amending my posting. The song is, I think, by Jim Woodland. These four lines only are the chorus
Chorus
Phoebe Webber has been slaughtered on the fields of Peterloo
And the red upon the green grass sparkles like the morning dew.
Feel the tears roll down like water, and wash the bloodstains from you.
Phoebe Webber has been slaughtered on the fields of Peterloo.
