The more this thread goes on, the deeper the hole you are digging for yourself, Conrad and the harder it will be for you to get out.

You say

Actually at my events there is no audience- everyone is an equal participant.

We've been doing that for years here in the UK. We call it a singaround. Don Firth has been doing it a long time, only he calls it a "hoot". Nothing original there, then.

All in all, Conrad, I find it hard to find anything original in what you are proposing. It has all been done before. The only difference is that most of us don't have the contempt for professionals you have.
