DJ Dave Lee Travis indecently assaulted a 19-year-old woman during a recording of 'Top Of The Pops', a court has heard.
The 68-year-old carried out a series of assaults which were "sexual in nature" while working as a disc jockey, acting in pantomimes and even at the opening of a hospital radio station, London's Southwark Crown Court was told.
The former BBC Radio One DJ, whose real name is David Patrick Griffin, is on trial accused of assaulting 11 women, one of whom was 15 at the time of the alleged offence.
Prosecutor Miranda Moore showed the jury a short clip of Top Of The Pops from 1978, in which it is alleged Travis is starting to assault a woman.
The 19-year-old had travelled to the show with a friend and alleges Travis put his hand up her skirt to "touch her bum".
Ms Moore said the teenager "pulled away from him very quickly" and added that her friend was "aware of something happening".
Travis, from Buckinghamshire, is charged with 13 counts of indecent assault dating back to between 1976 and 2003, and one count of sexual assault in 2008. He denies all the charges.
He was arrested under Scotland Yard's Operation Yewtree, which was prompted by abuse allegations involving the late Jimmy Savile, the court heard.
Earlier in the day, Ms Moore said women had come forward from "all parts of the United Kingdom" with similar allegations against Travis.
The trial continues.
