20469 Dudleymoore           Discovered 1999 July 13 by J. Broughton at Reedy Creek.
Pint-sized british comedy actor and musician, Dudley Moore (1935-2002) collaborated with Peter Cook and others to help create the 1960's satire boom that has been reverberating ever since. "Pete and Dud" are fondly remembered for their obtuse dialogues in guise as working-class lads in raincoats.
