I think it would be fair to say thet the MU concerns itself more with the interests of professionl and semi-profesional musicians than the interests of music-making in general. Where these may clash or be unclear, the issue will quite understandably be seen from the point of view of the majority of their membership.

The problem here is one the freedom of public expression in largely un-paid events, not one that the majority of its hard-gigging members are too interested in.
