Pip asked, do Genie and I agree or don't we. To quote mg, "I know we differ in some areas and agree on others."

Your selected quotes, however, seem apples and oranges, since I don't think we used "performance" in the same sense; note my explicit quotes. Also, I've expressed no views on group singing. I certainly have no objection to singing better or more concertedly when it's feasible. She was suggesting a helpful option, not attempting to impose an arbitrary standard on others. I'm too much of a folk diva to pass around song sheets--I prefer to hog the limelight--but I'd use one if offered.
