Robb, I also love Margaret Rutherford! I only discovered a few years ago that Petula Clark was a child star in Britain and not only a singer. I'll be glad to see her performance as well.
I recently watched an interview with Stephen Fry where he gave his opinion as to the difference between British and American humor. He believed American comedy was based more on laughing at others, while British comedy was based more on laughing at ourselves. Maybe that's why I prefer Britcoms! Cheers to all, Bowers
