Jurors in the trial of veteran entertainer Rolf Harris have been shown footage of a TV game show starring the artist in Cambridge in the 1970s - despite the star telling them he had never been to the city until three or four years ago.

The jury at London's Southwark Crown Court was shown clips from an episode of a show called Star Games, filmed in 1978 in Cambridge, in which Harris - who lived in Sydenham, during the 1960s and 1970s - competed.

Admitting that it was him in the programme, Harris denied deliberately lying, saying he had forgotten about the show, and did not actually know he was in Cambridge at the time.

Harris, 84, faces 12 counts of indecent assault against four alleged victims between 1968 and 1986.

One of his alleged victims, then aged 14, claims he groped her bottom outside what she thought was a celebrity It's a Knock Out event in Cambridge, describing him acting up for a crowd by barking at a dog before he grabbed her. She believed the date to be around 1975.

The court previously heard there was no independent evidence to put Harris in Cambridge in 1975, and the artist told the court he could not have committed the offence as he had not been to the city until a few years ago.

Giving evidence last week, he said: "I went once, a couple of years ago, for an art exhibition of my paintings and that's the first time I have ever been to Cambridge."

But today the court heard that new evidence had emerged in the form of video footage of the 1978 Thames Television programme Star Games, filmed at Jesus Green in Cambridge, in which Harris took part as a team captain and also competed in a swimming race.

The jury of six men and six women was shown the beginning of the hour-long show, introduced by Michael Aspel as being in Cambridge, and describing Harris as a team captain.

Prosecutor Sasha Wass QC put to Harris that the event was the one that the alleged victim had described.

She said: "That video supports pretty much everything that (the alleged victim) said apart from the year, she has got the year wrong?"

He replied: "By three years, yes, she is out by three years."

Ms Wass said: "But when you told the jury with such confidence last week on Tuesday that you had never been to Cambridge until four years ago, that was a deliberate lie, wasn't it?"

He replied: "No, it wasn't. I didn't find out that it was in Cambridge until I saw the video played back and then at the very opening the voiceover introduced it over what I remember was a helicopter shot of the field.

"That was the first time I had heard the word Cambridge."

The veteran told jurors: "I had no idea. I don't think any of us knew."

Ms Wass asked: "Nobody knew they were in Cambridge?"

Harris replied: "None of the performers, none of the stars knew."

He told the court the performers had probably gone in a bus or coach to the green and he would not necessarily have known where he was.

He also said that what the alleged victim described as a marquee was not something he would have recognised as a marquee.

Harris said: "I was there but I didn't know it was Cambridge."

Ms Wass asked: "Are you saying that you entirely forgot that event?"

He said: "I did until I saw the video and then I remembered it all."

Pressed further by the prosecutor, the entertainer said: "I'm doing hundreds of events during the year, going to Australia, Canada, New Zealand, South Africa.

"This was 36 years ago you're talking about, 1978, not '75 as you stated earlier."

Putting it to Harris that he had suggested that the alleged victim lied, Ms Wass said: "I'm going to suggest that you are the one that has lied and that demonstrates it, and that there is no way you could have forgotten that event and you deliberately tried to mislead the jury when you told them that you had not been to Cambridge until four years ago."

Harris said: "I had forgotten that event until I saw that video"

He said he had not deliberately lied, but it was a "lapse of memory".

The jury was shown the opening scenes from the show, which introduced three teams - one led by captain Harris.

Other famous faces included singer Joe Brown, Monkee Davy Jones, actor Julian Holloway, On The Buses star Anna Karen, and actress Rula Lenska.

Harris was seen in one clip appearing to mimic a kangaroo.

Ms Wass went on to put other allegations to Harris, including from a woman who claimed she was groped repeatedly by Harris while she was working as a television make-up artist in the 1980s.

The star denied her claims, and added that it was unlikely she would have been applying powder to him because he was allergic to it.

He also dismissed claims by a mother and daughter who said he first assaulted the girl, then later rubbed himself against her mother, during an event at a small hardware shop in Australia.

Harris said he did not remember the mother stamping on his foot and telling him he was a "disgusting creature".

Ms Wass said that while Harris claimed his alleged victims were all making up their claims, the new evidence of the film showed that he had lied.

She said: "That film footage which has come to light very late in the day... will demonstrate that it is not these victims who have lied, it's you who have lied. And you hoped to get away with that lie when it came to (the alleged victim who claimed she was assaulted in Cambridge)."

Harris said: " I didn't realise it was a lie, I had no recollection of being in Cambridge until I saw that video."

Ms Wass said Harris "can't have failed to know" that he was in Cambridge and told the entertainer: "The footage shows that you have lied during this case as you have lied about every other victim."

He said: "No, not lying. I just had not remembered anything about it until I saw the video."

Asked by his own barrister, Sonia Woodley QC, if he deliberately lied or misled the court, Harris said: "Well, it wasn't a deliberate lie. As far as I remembered I had never been to Cambridge and, until I saw that opening couple of frames of that programme, I had no idea that programme was done in Cambridge."

Ms Woodley asked Harris if he had been accused by daughter Bindi of molesting her friend - one of the alleged victims in the case.

The entertainer said: "Not as far as I remember."
