Vrillon Transmission: 1977 pirate TV message from space alien

Over at the Daily Grail, a post pointing out the similarity between a Man Of Steel viral video and the utterly fantastic "Vrillon Transmission" of November 26, 1977, when a representative of the Ashtar Galactic Command hijacked a UK television transmitter during the nightly news to share the above message from our space brothers and sisters. I'm not sure why people say that the source of this pirate transmission has never been identified when he clearly says that his name is Vrillon.
