du LIebe Augustin - why do I know this tune for summat else? in Tunes /Songs Posted October 31, 2012 Righteeho!!!! Now the trickier part - if the peasants were using the melody back in 17thC as they dropped like flies that must mean it has been around since then. I already tried and failed to get a source by playing the youtube into several "name that tune" sites I assume David's lassie is not the same as a Bonnie Bonnie lassie?? Did you ever see a lassie, I suppose someone on mudcat might know but I would be frightened to go looking over there at night without a head torch!
