They repeated that pilot on TV some years ago. I think it was on TVLand, when they were starting to show The Dick Van Dyke Show (this was a long time ago, come to think...) The pilot is really interesting, in that the basic idea is there, but it's all so different.
BTW, for years and YEARS growing up, whenever I heard of a "Van Dyke" beard, or the painter, I thought of the show.
