Here's the finale of the source of yesterday's "Name That Unlikely Variety Show" clip - the cast gathers to perform then-popular hippie anthem "Age of Aquarius".
And oh, what a cast... Englebert Humperdinck, of course. Gladys Knight and the Pips. "Skiffle King" Lonnie Donegan. Sid Caesar and Jack E. Leonard. Groovy, man.
At the risk of hyperbole - this is the greatest performance of any kind, ever.
