As arranged by Cohen Braithwaite-Kilcoyne, who is teaching me concertina.
From Playford's Dancing Master, 1726 edition.
I'm playing a 30-key C/G anglo made by Holden Concertinas. You can read more about this instrument here.
I am ridiculously happy with this instrument and with what I've managed to do with it in a year (thanks to the complete disruption of my social life). Though I should warn beginners that I play many other instruments including, critically, melodeon, and that has definitely helped. This is however the first time I've felt able to share a video with people who aren't close friends.
