I've posted several new concertina videos on YouTube over the last few months that I haven't alerted anyone here to, so I shall in case anyone's curious. Nothing Irish though. I played them on a Wakker Hayden duet with 46 buttons. I have a few bones videos there too, and one on anglo concertina.

(Ignore the thumb wrestling one, it probably isn't very funny unless you were there).
