The piper in the cave
I heard this one is played as a march. Seams also known as Piper’s Cave.
It is taken from album "Stay Another While" by Paul O’Shaughnessy and Frankie Lane, track 2. https://thesession.org/recordings/display.php/2072
John Doherty, Co. Donegal used to play it and reportedly said that it was about a piper who attempted to make an underground journey through the caves twixt Maghera and Glencolmcille . He said that it was the last tune the piper was heard to play before he et by some wild beast ( as reported by Pádraig September 18th 2004 ).
Quite different story from celticrichie (September 18th 2004) :
"(…) I have been told that The Pipers Cave refers not to some romantic setting, but to a bar somewhere in North Africa during WW2. A better setting by far you might say."
Nice one anyway.
What you posted is in A dorian, not G major. Paul O’Shaughnessy plays it in B though…
There is another Piper’s Cave on Colonsay with a similar story. The piper was attempting to go to Hell and back when drunk - he disappeared into the cave playing "MacCrimmon Will Never Return" accompanied by his dog. He was never seen again but the dog emerged at the other end of the island smouldering.
There is a corresponding Scottish pipe reel of the same name, with no resemblance to this one - it is also played in Ireland as a polka, the name of which I forget.
