Review of Barefoot in the Park

I absolutely loved this version of Barefoot in the Park. I have an old copy from when it first aired but its so grainy its really hard to enjoy. I would love to find another copy somewhere. If anyone knows how to get a copy please let me know. This stage production was so much better than the movie, its scary. The actors are wonderful and the movie version appears drab and lifeless in comparison. I have searched all over the web looking for this movie, but I guess it isn't out on video at all or I would have found a copy by now. If anyone has a copy and would like to copy that, I would be willing to buy it. If anyone know of a website that sells old HBO movies, let me know.
