Footage from the 1964 BBC2 Beyond The Fringe special
, with the late, great Dudley Moore playing a Diabelli Variations-style take on the Colonel Bogey March by F.J. Ricketts. (That's the theme that was used in The Bridge on the River Kwai.)This is essential viewing if you're a fan of stellar pianism--or P.D.Q. Bach-type humor.
Enjoy.
