The other day, Evan (of Skeleton Hands) hipped me to the fact that Paul McCartney paid sideways tribute to Ron Mael of Sparks in the video to McCartney's 1980 hit, "Coming Up". I had not been aware of the video before, but in it, Paul (and Linda) McCartney green-screen themselves into a full band, including impressions of a couple real-life musicians -- among them, Ron Mael. "Ron" is the keyboadrist, on the right side, in a white shirt and black tie:


McCartney got the personality dead on, but looks like he chickened out a bit on the moustache. (Ron has a Chaplin 'stache, whereas Paul in the vid has merely a smallish one.)

Edit: Evan just hit me up with this gif from the vid:


Good job internet!
