The Irish have a perverse mindset that usually seems to make instruments do what they don't want to do- the bagpipes naturally play continuously, so they stopped them on the knee. You need to breathe to play the flute, so they chose an uninterrupted legato style. The B/C or C/C# box is played of course in D and G. And the Irish language is almost all consonants when written, but practically none are pronounced.

They used to run a miscellaneous instruments section for things that didn't fit into a regular competition- a friend once "won" the section at a local fleadh for playing the Continental chromatic accordeon, which he did very well.
