Sam, as Liam wrote it's all on TG4's website http://www.tg4.tv/
It's an Irish language channel, but there are subtitles and it's
surprising how much you a non-Irish speaker can pick up just by
listening, easier than trying to read Irish I find, and music is a
universal language. You'll find many interesting Irish trad. Programs
there including Meadh O'Hare & Conor Byrne's Traveller musicians series
and lots more.
