That video is all about one of my favorite theories, which is that Numan was influenced by Foxx while he was in Ultravox, then Foxx went solo and was in turn influenced by Numan. I might have gotten it wrong, I suppose, and the influence could be entirely one-way from Foxx to Numan, but I feel post-Ultravox John Foxx (namely Metamatic) seems to take something from Numan that Numan couldn't have taken from Ultravox because it wasn't present. I mean, Numan had the Ballardian futurist thing happening (see Pleasure Principle) before Metamatic or "Underpass." The second or third Ultravox album had seen them move from a guitar-focused post-punk sort of feel into new wave modernism but I don't see where Numan took Pleasure Principle or Telekon from Systems of Romance.
Somebody needs to write a thesis mapping out the flow of influence between the various British bands in orbit around, and downstream from, Bowie -- including Roxy Music, Ultravox, Japan, Duran Duran, and many more.
Oh, and... eyeliner is one thing on young dudes, but it becomes sort of strange after 50.
