Here are the dots, PDF and video for the Dark Girl Dressed in Blue, also known as The Duchess (at least to me and Kerry Fletcher, can’t find it listed as this anywhere else!) and as Over the Waterfall in Old Time circles, albeit with the A and B sections reversed. There appears to be a song version of the tune dating back to about 1850, with lyrics by music hall star Harry Clifton (1824-1872), though recordings I can find are to a slightly different though seemingly related tune.
