The first pop video? This is a scene from the 1970 film Performance, starring Mick Jagger and James Fox. My Adventure Through Film explains their two characters:
Chas, played by James Fox, is a violent gangster living in a rough part of East London. Though he takes great pleasure from his work, he is often not given the respect that he deserves from his boss. After carrying out a hit that was not supposed to happen, Chas leaves town to lay low for a while. This is where he meets the eccentric retired rock star, Turner ...But Fox is brilliant too. Originally a child star who had his own Ealing Comedy (The Magnet), Fox was best known before this for playing effete aristocrats (The Servant) or preppy song-and-dance men (Thoroughly Modern Millie), he is utterly convincing as an East End gangster.
Played by Mick Jagger, Turner is a drug and sex addicted former rock star who has disappeared into retirement in order to write a memoir. Jagger is nothing short of brilliant in this role. He oozes with dirty and bi-gender sexuality that is actually a little confusing.
His subsequent religious conversion and disappearance from films for a decade did nothing to harm the cult reputation of Performance.
Fox reappeared in the 1980s but now seems inextricably confused in the public mind with his brother Edward. (Clue: James is the one who can act.) He is now the father-in-law of both Billie Piper and Richard Ayoade.
