I believe that "Famous Ladies of the Silver Screen" series that John Springer did with Bette Davis, Joan Crawford, and others did play an hour of selected film clips before the star came out to answer questions for an hour. Grant's show obviously did not repeat that formula.
What a wonderful trip to look forward to (well, I'd forgo the squid, but that's just me). Hopefully you'll be back up to full strength by then. Sorry for your abominable luck.
