A bit of Pete and Dudley
In 1971, Peter Cook and Dudley Moore brought their comedic stylings to Oz. During their tour, the pair filmed a two-part special that screened on the Nine Network. Apparently, it wasn't repeated until 2005 when an edited version entitled "Pete And Dud: The Lost Tapes" aired in Britain. Now the uncut shows are available on the DVD "Behind The Fridge" (as opposed to "Beyond The Fringe", a 60s theatrical revue in which Cook and Moore starred).
Contrary to what it says on the case, the black-and-white footage runs for about two hours. The production's largely studio-bound, the sets/props are rudimentary and, apart from a flashback sequence featuring a hot babe, there are no other performers. And yet it enthralls. This is "A Bit Of Fry and Laurie" (which I adore, don't get me wrong) done 15 years earlier, weaving intellectual satire and absurdity in lengthier, semi-improvised(?) skits, and with better piano playing.
