On Wednesday (October 3), an ITV programme that alleges the entertainer sexually assaulted young girls at the height of his fame will air. The documentary includes testimony from several women who say that they were abused by Savile as youngsters.
The Sun reports that the footage also includes details of an interview the former Top of the Pops presenter gave after Glitter's arrest over illegal images of children.
Glitter - real name Paul Gadd - was arrested in November 1997, after pornographic images of children were found on a laptop that he had taken for repair. He was sentenced to four months in prison in 1999.
The musician was subsequently convicted of child abuse charges in Vietnam, resulting in his being placed on the sex offenders' register for life in the UK upon his return to the country in 2008.

Savile, who died in October 2011 at the age of 84, reportedly said during the interview: "Now Gary, all he did was to take his computer into PC World to get it repaired. They went into the hard drive, saw all these dodgy pictures and told the police, and the police then said, 'Oh we've got a famous person, yeah, we'll have them'.
"But Gary hasn't sold 'em, hasn't tried to sell 'em, not tried to show them in public or anything like that. It were for his own gratification. Whether it was right or wrong is of course up to him as a person.
"And if you ever said to that copper, 'What's Gary Glitter done wrong?' Well, nothing really. He's just sat at home watching these dodgy, dodgy films."
Savile's nephew Roger Foster said yesterday that his family were "disgusted and disappointed" by the claims made in the documentary, saying: "I think it's very, very sad you can say these things after someone's died and the law says you can't defend yourself when you're dead."
