I just noticed [the question about the '50s story](https://scifi.stackexchange.com/q/203976/19561) which ends with the discovery that "the whole block's a rocket ship!" The story is Richard Matheson's "Shipshape Home."

I heard this story late at night on the radio when I was about 13. I liked it and so did my friends. We all went around saying "The whole block's a rocket ship!" for quite a while. (We lived in NYC, so it seemed quite reasonable.) 

Years later, I told my kids the story. I did discover at one point that the story was "Shipshape Home" but what I'd really like to find is the radio show that I heard. It's probably not available — because I have tried looking at Old Time Radio websites — but I just thought I'd ask. 

Does the radio show with that great ending — "The whole block's a rocket ship!" — still exist? Can I download it?
