You can watch a lot of Irish music TV programmes over at tg4.ie (the Irish language channel). In the most recent one in the Geantrai series you can catch some nice Anglo-concertina playing from Claire Keville and Jacqueline McCarthy, but also a rare glimpse of Charlie Harris playing one of those lovely old black Paolo Soprani boxes.
In Irish circles you often hear Charlie Harris' name mentioned as a tuner and C#/D player but you don't often get to hear him.
Go to
http://tg4.ie, click on the webTV button, and when the console appears, click Ceol - Cartlann in the menu at left. Choose Geantrai 2/12/2007 and you're away.
Charlie Harries appears at about 6 min 20. He doesn't look altogether happy to be on camera, it has to be said. Incidentally he gives an eloquent demonstration of the no-fourth-finger-style of playing - just so you know I'm not making it all up.
And astonishingly, banjo player Des Mulkere, who appears on those clips of Joe Cooley just before Cooley died, looks possibly younger than he did in 1973.
