Listening - briefly - to that Comhaltas clip reminded me of something Paul Jennings wrote once about being at a party where someone decides to play a few tunes on the piano. The melody is fine, but unfortunately the pianist only knows one chord, which he plays repeatedly throughout, "giving every tune a mournful Hebridean feel".

The first time I read that I laughed so much I had to put the book down - you can just hear it. (And I think I've just heard it again.)
