After an early career as a singer (he sang backing vocals for
Tiny Tim) and actor, in the early 1970s Hall became a publicist for
EMI Records. There, he worked in the
Artists and Repertoire department, where he met and befriended
Freddie Mercury, he also claimed the song, "
Killer Queen" was written about him, despite Mercury stating it was about a
call girl. In 1986, a chance meeting with
Steve Perryman led to him becoming a football agent, and within 10 years he had built up a roster of about 40 well-known clients, including
John Fashanu,
Robbie Savage,
Tim Sherwood,
John Scales,
Neil Ruddock,
Dave Beasant,
Paul Walsh,
Dennis Wise, and
England team manager
Terry Venables. As an agent, Hall helped raise the status of footballers, negotiating for large salaries, appearance fees, branding rights and other commercial bonuses. In 1996, Hall was a regular guest on ''Caesar's Rude Arena'' for
Television X, hosted by
Caesar the Geezer, in which he referred to callers as "bubbeleh", thus revealing his Jewish roots. Hall can be seen in the July 1973
BBC Television Man Alive documentary film "Twinkle Twinkle Little Star", as one of a group of EMI men promoting 11-year-old boy singer Darren Burn and his first single. The programme was first broadcast in October of that year. ==Radio presenting==
