Not as music situation, but: was watching an amateur, but professional quality, little theater performance, done by
two "elderly" seated characters, when an audience member got
up on stage and proceeded to take close-up photographs of the
performers. The only thing to be said for him was, he didn't
keep it up for more than a minute or so. There was kind of a
wave of "gasp" through the audience. The guy was something
of a known dipstick, but to my knowledge that was his
crowning moment.
