I'm aware that Herr Fraser lives in California since the late seventies where the sun shines a lot and that he was/is - like many Californians - rather body conscious (as his penchant for open shirts shows), but I don't think he achieved that shade of a tan!
Or more bluntly: The bass player in the clip is black, Fraser wasn't and to the best of my knowledge still isn't.
Pigmentation aside, the whole look ain't right either. By the early eighties, Andy was a gay man having come out of the closet and to grips with his sexuality which he had denied in the seventies (his first gay experience was very long after his Free career, he writes on his web site, and it took him some time to come to terms with it, he was a hetero-married man and had children). Accordingly, he had changed his look from hippie child to something a little more alluring to men similarly inclined.
And finally: Fraser always had a chip on his shoulder about wanting to sing and not being allowed to be the lead singer - having Paul Rodgers in the band really doesn't help your aspirations in that respect. He even left The Sharks because he couldn't stand Snips' singing and felt he could do a better job. By 1980 I think
he would have gladly sung together with Robert Palmer, but certainly not played solely bass in his backing band (incidentally: Palmer was a capable bass player in his own right, it was his favorite instrument and he did a lot of writng on it). Andy had worked years getting away from the image "Andy Fraser - the (hetero) Free bass player" to "Andy Fraser - the (gay) singer and songwriter". (I find his singing a bit affected and will eternally prefer his bass playing, but it doesn't mean anything to him anymore judging from more recent interviews.)
If now someone makes a case of this being Andy after all than I stand corrected!!!
