I heard a bit of that Radio 4 discussion. If anything, pseuds being "funny" are worse than pseuds being serious.

Actually, I quite like the idea of saying "let's all shut up and listen instead", in a concert, or in any other setting - it's the kind of thing Quakers, and people who've been around Quakers, do in meetings when they are getting over heated. Perhaps that is really what lies behind the Mudcat outages...

But the joke about "here is a composition" rapidly gets very tired indeed.
