The Voyager spacecraft was launched in 1977 with many objects on board, a floating time capsule, and … maybe … a message to whomever might find it on the other end, light-years away. Included was the “Voyager Golden Record,” a disc containing music from all around the world. (You can see the sort of stuff included on the record.) It was meant to be a: “Hello, there. Here is who we are.” Chuck Berry’s “Johnny B. Goode” was on that record.
On Saturday Night Live in 1977, Steve Martin imagined what the alien response would be to all the material we sent them.
