Bowie's intense performance of "Fame" on the Cher Show 1975

I had seen Bowie and Cher's disco goofball Young Americans medley from her show, circa 1975 (where David still manages to rise about the cheese), but I can't believe that, until last night, I'd never encountered this rather singular performance of him singing "Fame" on the show. As the video description points out, this performance uses a different backing track for him to sing to than the one found on the record, also making it extra special.

Fame, what you need is in the limo
Fame, what you get is no tomorrow

If this track, that Carlos Alomar guitar strut, and that rhythm section don't make you at least think about clucking around your hab unit like a funky chicken, you ain't doin' it right.
