Anyone noticed "There's Whiskey in the Jug", 1858 (with music), on the Levy collection website? It's only slightly later than the earliest (Hodges) issue of "Whiskey in the Jar" on the Bodleian Ballads website, and earlier than the other 3 issues there. The girl is Molly in these. Is Jenny found before the 20th century?

When was "Patrick Flemming" reworked into "Whiskey in the Jar"? c 1850?
