The National Library of Scotland has put on line an article on the broadside, "The Murder of Betsy Smith," which seems to be the antecedent of "Jealous Lover." The broadside by McIntosh of Glasgow is reproduced in facsimile, and given a date of mid-nineteenth century. The Bodleian copy of this broadside about a murder in Manchester is damaged.
