Hello Paul !
Thanks to answer so quickly.
I agree with you about the Donald Davidson tune I have found here :
It is also the same given by "The Session".
But it is not the tune I am looking for ; listen to this youtube clip :
the second tune at about 1'16.
This tune is played here in Brittany and presented on four internet sites at
least ; it sounds as an Irish tune and its name sounds rather Scottish.
The solution will be this perhaps :
In Gibraltar there was in the 79th Regiment two musicians : a Scottish who
composed a march and an Irish who composed a reel. That would be a
surprise, would 'not ?
No, only a joke from me !
So the reseach goes on !
Have a good a day !
