Ashtar Galactic Command Recording ITN, ITV 1977 PIRATE transmission of reported alien origin

Description from Wikipedia, I find the description accurate. This happened in 1977 and the transmitters should have shut down when the signal broke in.

A speaker interrupted transmissions for six minutes and claimed to be a representative of an "Intergalactic Association". Reports of the incident vary, some calling the speaker "Vrillon"[1] or "Gillon", others "Asteron".[2][3]

The voice, which was disguised and accompanied by a deep buzzing, broke into the broadcast of the local ITV station Southern Television, over-riding the UHF audio signal of the early-evening news being read by Andrew Gardner from ITN to warn viewers that "All your weapons of evil must be destroyed" and "You have but a short time to learn to live together in peace."

The interruption ceased shortly after the statement had been delivered, transmissions returning to normal shortly before the end of a Looney Tunes cartoon. Later in the evening, Southern Television apologised for what it described as "a breakthrough in sound" for some viewers. ITN also reported on the incident in its own late-evening Saturday bulletin.

The broadcast took over the sound only, leaving the video signal unaltered.

I appreciate the premise, and I swear I typically try and support this type of thing, but the first thing that jumps out to me, is that Vrillon has a British accent.
I was watching a show from science channel called "Are We Alone?"
Is that really still a question people can in all honesty pose to themselves?
