Hi Jenny,
Don't quite see how this is going to help you spend more time practising

but
There have been a couple of very enjoyable programs recently on TG4, the Irish-language TV channel. Go to
http://tg4.ie/Bearla/Webt/webt.htm and click on the big WebTV button if the console doesn't appear immediately. In the menu, choose Ceol - Cartlann. Look for two Sé mo Laoch programs - one on Joe Derrane, and one on Tony MacMahon. Subtitles in English. Lots of stuff apart from closeups of keyboards and bellows, of course, but good for your general education...
This page lists a few clips (shown in blue)
