I was going to leave this (yet another) going nowhere threads, but Carroll`'s attempt at guilt tripping:

"You didn't respond to my Walter Pardon example, so presumably you would be prepared to discomfort a nice old singer at one of your club nights"

This quite simply beyond the pale, though why I sould be surprised by this response, I don't know, it' typical!

I have no idea which part of " it's ultimately the musician that makes the decision as to whether there is audience participation or not, during her/his performance" Carroll doesn't understand
