I played them on the Cello 35 years ago.
Now, has anyone (...) attempted to play the bourrée?
Yes, that's the standard way to play this kind of movement: Bourrée 1 with repeats, Bourrée 2 with repeats, Bourrée 1 without repeats.
Well, there are two of them linked and the first one is repeated at the end, it seems.
Here is my abc version. I have not based it on yours but gone back to the source and started from scratch (for both Bourrées). Like you, I put it in G so it fits on a treble English Concertina (the original is in C, an octave and a fifth lower, in the Cello range). To minimize confusion, I put the 2nd bourrée in G minor, fixing the accidentals as they come (and marking some unnecessary but otherwise potentially confusing ones as well).
And David B., if there are any corrections needed to the second bourrée, and you know what they are in ABC format, can you possibly send me the appropriate ABC coding and I will make the necessary amendments to the file in the tune-o-tron.
This version was specifically designed to work in the Tune-O-Tron converter, and it took some doing. Note I have put 5 bars per line (four makes more sense, but then there were too many lines to display and the bottom got cut off). Also, I have had to put the first two notes of Bourrée 2 on the same line as the end of Bourrée 1, before the key change (the notes don't change). The GIF, MIDI, and PDF generators all handled it OK in my testing.
