They're American, but they couldn't sound more British if they tried. (And they do).

And what could be more SF than a 60s Merseysound act getting attacked by a 60s Japanese monster?

Yeah, it's a terrible video but what could be more SF than a song about an alien that comes to earth, eats people, and is defeated by his fear of guitars?

not at all interesting story about this video: As a kid, I never saw it aside from brief clips on "K-Tel" commercials. It never happened to be on MTV when I was watching through my teens, but people constantly told me I "Just missed it."
