I was attracted to this poem because of its structure and rhyming pattern, which is similar to one used in a number of old ballad tunes.  However, I didn't like the way it ended.  The original poem was just three verses long and ended with Polly heartbroken.  This representation of the distressed maiden seemed to me very much of its time, with its appeal to masculine sympathies, but gender politics have moved on since then.  So I decided to add a sequel - the two verses in the right-hand column are mine and I hope Joseph, who clearly had respect for women, and especially working-class women, would approve.  I also altered the words a little, to make them easier to follow on a first hearing.  The tune is reminiscent of some Northumbrian dance tunes in 19th century collections.
