Speaking of Bowie, the BBC over Christmas re-aired a long-lost*, (believed erased) 1973 Tops of the Pops performance by Bowie of his then-hit "The Jean Genie." Really remarkable is that unlike most TOTP appearances, Bowie didn't lip-sync or use backing tracks. Live as life can be. (Mr. Bieber, take notes.)
*=Notice the fishlens shots? That was the cameraman's idea, and kept a copy so he could show off its use. He apparently wasn't aware until last year that performance tape was considered lost and he held the only known existing copy.
