Ex-BBC presenter Stuart Hall has admitted indecently assaulting a girl under 16 but denies 20 further charges.
Mr Hall, 84, is to go on trial accused of 15 rapes and five indecent assault offences against two young girls, allegedly between 1976 and 1981 in Greater Manchester and Cheshire.
The charge he admits was put to him ahead of the trial at Preston Crown Court.
The court heard the attack happened between January 1978 and January 1979.
Mr Hall, of Wilmslow, Cheshire, is charged with seven counts of rape against one alleged victim between 1976 and 1978, in Manchester.
Five of the rapes are said to have taken place when she was aged under 16.
He is also accused of two counts of indecent assault against the woman in the same period.
In addition, he is charged with eight counts of rape and three of indecent assault against a second alleged victim between 1976 and 1981, at various locations in Greater Manchester and Cheshire.
One of those alleged rapes is said to have taken place when the complainant was aged under 13.
At a trial last year, Stuart Hall was jailed for 15 months - later extended to 30 months by the Court of Appeal - for sexually abusing young girls aged between nine and 17.
The ex-host of BBC game show It's a Knockout was stripped of his OBE after he admitted 14 offences against 13 girls that occurred between 1967 and 1986.
