Listening to Shostakovich's concerto for piano, trumpet & strings I recall asking Gerard McBurney how it was that Shostakovich was quoting from the playground song "Poor Jenny is a'weeping" He told me that one of the professors at the university Shostakovich was working at was investigating English folksongs. But I also find that the tune is part of "La Bourrée des Galvachers" a composition of French folk dance tunes. Does anyone have any further info on how this tune came to be used in English playgrounds?
