THE BLUEBELL POLKA: THE FRENCH CONNECTION!

I have a CD issued on the French label Silex released in 1993. The title is Le Frères GUILLEMAIN Berry - Bourbonnais Silex Y225105. It is a compilation of hurdy gurdy duos or hurdy gurdy and pipes duos of the playing of the brothers Gaston (1877-1966) and Lucien (1868 - 1966) playing Central France traditional dance music. On a few of the 29 tracks Gaston plays with other musicians. On track 11, Gaston plays a hurdy-gurdy duet with Jules Devaux and they play The Bluebell Polka though it is just called Polka on this recording. One player plays the three parts of the tune fairly straight whilst the other plays a harmony part - which is at times outrageous in its audacity though it does not always come off.
All the tracks were recorded either in 1926 or after a long gap between 1957 and 1965. It ought to be able to recognise which are the earlier tracks but very careful restoration of all the recordings using CEDAR means that it is quite difficult to tell by just listening and the CD does not give the recording dates of each track. It would be really interesting to discover whether this French recording was made before or after then famed Jimmy Shand one.

One clue might be in the sequence of the parts on each the recording, I have always been puzzled as to why JS plays them in the sequence that he does. On the 1955 recording JS plays the tune:-
AA BB AA CC AA BB AA BB AA
On the Youtube recording taken from a television programme at
http://youtu.be/g3hAtxZXNrA
he plays it:-
AA BB AA BB CC AA
I suspect that both these sequences are more to do with the timing needs of television and length of time available to a shellac 78 recording than trying to fit the tune to the needs of a dance.
The hurdy-gurdy duo recording is sequenced:-
AA BB AA CC AA BB AA
which is the same as the first part of the Shand recording.
