Just researching related tune, Miss McDermot.

The files on JC's midis reveal it as almost identical to Princess Royal but in what sounds like a minor key, even though its labelled as Gmajor.

Here's a link to the midi in question,http://trillian.mit.edu/~jc/cgi/abc/tuneget?F=MIDI&U=http://www.novosaires.com/Partituras%20y%20midis/abc/p-q.abc&X=13643&T=MISS
it also sounds like another [unnamed] tune I've heard in sessions, anyone know?
