I would suggest that if people are this interested in the controversies surrounding Celtic Music that they find out about the many, many other instances of the very same things happening to other musicians who don't own the rights to their music.

In the U.S., Green Linnet has the U.S. rights to many artists back catalogues, and refuses to release them.

Why, when this practice is so prevalent, are people so shocked and indignant about this one circumstance? It has been happening to folk and blues musicians in particular, for the better part of this century.
