A few years ago, Dick Van Dyke and his brother Jerry appeared in a limited-run production of Neil Simon's play, The Sunshine Boys. I believe they only did it in two cities, and one of those was very close by, in Malibu. To my great annoyance I found out after-the-fact, so I never saw it. And this is one of those it's just teeth-aching to have missed. I believe that they had an offer to take it to Broadway, but as Dick said later the idea of them playing eight shows a week was just too much. (I believe he was 84 at the time. Jerry was 79. In fact, he also noted that he and Jerry were actually too old for the roles as written, since they're supposed to be in their early 70s. But then George Burns was too old for the part, as well, and that didn't hurt things...)
Well, though I didn't get a chance to see it on stage, here's a treat: an hour of that production. The sound isn't great, but it's definitely listenable. If you want to jump to Dick's entrance, it comes at the 10:30 mark.
