Oops, I hit the post it button too soon.
The cds I mentioned were just typical dance cds but they do list the tune names:
Sets and Solos Vol 1 & @
Kathleen Lavin - Step in Time
Billy McCommisky, Brendan Mulvilhill, Zan McLeod and Culkin School of Dance - One More Time
The last is unusual in that they have tunes at slower speeds than dancers normally use, as well as typical speeds, so that they can practice the steps more slowly. Interesting concept...
Manitas- The best link I can suggest for anything about Irish dancing is this: http://www.geocities.com/aer_mcr/irdance/index.html
There are links to basic background info, dance school and teachers, vendors (including sources for these cds, which otherwise would be hard to find.
