David,
Don't think they put such information on their website; you might have to contact them direct and ask for the information you require (not sure they give out an e-mail address for practical reasons). They are an extremely pleasant and helpful crowd there.
Also you might try contacting Sean Laffey of Irish Music Magazine direct - the same description applies to him in my experience.
If I come across a list which may prove useful I'll put it up - is it song or music you're interested in?
I take it you are not a member of Irtrad (you'd be buried under responses if you were). It's somewhat dormant at present, but worth considering.
