A friend sent me this link…

Some nice stuff, though for the little time I’ve listened, it’s newer stuff…
I had not heard of it before, but I have now. Thanks! 
Trivia: The guy who runs this show is the author of the astronomy program Distant Suns.
I like that station! 
They do favor stuff like Fairport Convention, Clannad, Steeleye Span and Christy Moore over pure-drop, but that’s OK with me. I’m sure I’ve heard Joanie on there a few times, anyway! 
If you just go to WWW.LIVE365.COM you can then select IRISH and there are 92 different stations to select from that all play some form of Irish music.
On the subject of online radio stations, I’ve come to find that I like RadioCelt.com. For whatever mood you’re in, they’ve got a station for you. My favorite remains with the Trad, though.
