I get where Backwoodsman is coming from. I'm thinking this is about context, a sense of what people expect where. In a context where the emphasis was perhaps on camaraderie, welcoming offerings from all, perhaps a private social oriented get-together, no money charged on entry, free butties for all, I could put and do up with performer shyness. In a more public 'performance' focussed context, one might expect a little more.
