The copy of the song in 'The Festival of Anacreon', 1789, gives the tune citation as "To the hundreds of Drury I write", which is the first line of an English single sheet song entitled "The Bowman Prigg's Farewell", c 1730. I suspect "The Night before Larry was stretched" was an imitation, but, though I have the tune, I've never found a text of the song. [Cant- a bowman prigg was a pick-purse]
