Last month, when Dudley Moore's brilliant Britten/Pears parody from Beyond the Fringe was all the rage, I spent some happy hours revisiting the classic Dud 'n' Pete routines, but there seemed to be no more musical riches available. That's changed, thanks again to poster giebergoldfarb. Here's Moore doing Weill and Beethoven. Priceless!
Update: Alas, as Richard Friedman notes in comments, the party's over. The offending videos have been safely removed from the public arena. Oh, but didn't we have fun while it lasted?
