Shimrod must have an awful time of it being driven to distraction on such a regular basis. How embarrassing for performers to feel the sheer hate emanating from him, at times like this.
It rather confirms my view that there is a lot of intolerance out there.
A longtime ago I decided to listen and try to enjoy all performances, regardless, especially if they are being provided for no reward. I am a little more critical if I have paid to see artists, but that is the beauty of festivals, you can vote with your feet without offending anyone, by going to the bar!
