SO sorry, the link didn't work. I tried, honest.

I am now listening to a video
(one of those videos with a stationary photo, just listening)
of Anna Russell at the Sydney Opera House,
doing her reader's-digest version,
not of Wagner's Ring cycle which everybody knows, but

of Mozart's Magic Flute. I have never heard this routine before.

And the brilliant thing is that when Anna Russell did one of these,
she stayed as close as possible to actual musicological research
and verifiable data. Of course her delivery makes people laugh,
but she is using literal, historical information.
