It sure would be nice to make recordings of all the wonderful music at Eisteddfod, and to sell them, but who would do the work? I don't know very much about making recordings, but I believe there are technical procedures to make sure that the recordings sound good. It would be necessary to get permission from musicians, track down copyrights and get permission to use copyrighted songs, and then package and market the recordings. Who can do the work? The web site of the Folk Music Society of N.Y. http://www.folkmusicny.org
tells how to contact the society's officers with your suggestions. If it can be done, it would be a really good idea.
