The Far in the Mountains reference is wrong; the broadside was called 'The Unkind Parents, or, The Languishing Lamentation of two Loyal Lovers'. The Bodleian dates Bates' operation to 'between 1685 and 1714'.

The broadside has 16 verses. That's more than I feel like typing out just now; fortunately, though, there is also a copy in the Samuel Pepys Collection (5.322):

The Unkind Parents.
