Wrong Handed Piper?

[Chas]

I just watched BBC2's 'An Island Parish'.

Part of the story was a good-bye party for a long serving parish priest. All sorts of entertainments were planned and performed. One of which was a piping display. Three pipers marched in, the middle one piped 'right-handed' or should that be left-handed? I don't know how to explain it. The pipes were under his right arm.

I have never heard of this before. Is it common or even really possible?

Regards

Chas
