I've been to a fair few sing a rounds and such with Pierre. Many situations where the quietest performer is usually overwhelmed by background chatter. PlC is not one of those. He is a lover (listener) not a fighter (talker). If he believes he was not loud enough to disrupt the performer, then knowing him as I do, I support him.

Evidently this performer was maybe hypersensitive, upset about something else entirely or as Jack said the sound in the room really does come over strong.

Still, it is poor behaviour to shush. It is not a class room and the performer is not a teacher. A lighter joking admonition or honest explanation would have been better way to handle the situation.

I agree with the texting on mobile phone thing. Bugs the hell out of me.
