I have just read the JCHR report.   They seem to miss the rather obvious point that if the Act does apply equally to amplified and unamplified music, it is very hard to see how both applications cn be proportionate. They hardly note at all that the exemption for Morris discriminates against other European (and other) cultures. They fail to note that the incidental exemption and Sky TV exemption do not provide for respect for private lives and homes. My impression is that they have been nobbled somehow.
