The off-Broadway play?

There was an off-Broadway production of Really Rosie in a New York theater in 1980 - 1981, where it ran for 247 performances I think. I have the listening tape that records this play. I was wondering do they have the play on video or DVD?? Personally I doubt it. But why would they create a listening tape of the play and not a video? Seems like they would make a video before a listening tape. But I really want to see it if they do. Thanks.
