Hi Mr/Mrs/Ms/Dr/Prof Itus, may I then take the liberty of adding 2 links to my favourite UK concertina player? It's Chris Sherburn, who has been mentioned once on this thread. He plays a Dickinson Wheatstone anglo and currently plays in 2 duos who tour regularly in the UK.

1st duo is with his long-term Irish partner Denny Bartley:

2nd duo is with his English partner Bella Hardy, with whom he appeared on BBC4 at the Folk Proms:
