Channel Nine has featured a controversial song choice in a new ad for the 2023 Australian Open. 

On Tuesday morning, the network aired a promo starring tennis ace Novak Djokovic, with the song Rock N Roll Pt 2 by disgraced paedophile Gary Glitter as the backing track. 

The ad begins with a shot of a beaming Djokovic playfully wiggling his bottom as he prepares to return a serve. 

Djokovic starts dancing, before suddenly transforming into DC Universe villain The Joker - a reference to the Serbian star's nickname 'Djoker'. 

Rock N Roll Pt 2, which was also played during the iconic staircase scene in Todd Phillips' film Joker, blares in the background.

British glam-rock singer Glitter, born Paul Francis Gadd, was jailed in 2015 for abusing three young girls, and is reportedly due for release in a matter of weeks. 

The 1972 hit Rock N Roll Pt 2 is regarded as sporting anthem, and is often played at live events despite Glitter's dark past.

Glitter found fame in the 1970s as part of the glam rock scene, scoring number one hits with I'm The Leader Of The Gang (I Am), I Love You Love Me Love and Always Yours. 

He was first jailed in 1999 after pleading guilty to 54 offences of making indecent photographs of children under 16.

The singer was disgraced two years previously when a computer technician discovered thousands of child porn images on his laptop while servicing it.

Glitter was then jailed in Vietnam for two years in 2006 for sexually abusing two Vietnamese girls, who were aged 10 and 11.

In 2015, he was sentenced to 16 years in prison for historical sex offences against three girls between the ages of 8 to 13, at the height of his fame in the 1970s and 1980s. 

He was found guilty of one count of attempted rape, one count of unlawful sexual intercourse with a girl under 13, and four counts of indecent assault. 

Now aged 78, Glitter will reportedly be released from prison in a 'matter of weeks' after serving just half of his 16-year sentence.

Sources in the Ministry of Justice reportedly told The Sun earlier this month that the 'nature of his determinate sentence means the case won't go to the Parole Board.'

'It simply means that as soon as his sentence is over, he is free to walk out of the prison gates,' the source added. 

They said that Glitter had 'kept his nose clean in prison' so his sentence will be nearly over.

An offender who is convicted of a sexual offence is released on a strict licence.

The terms of the licence can include staying in an approved premise, obeying a curfew and having GPS tagging, not having unsupervised contact with children and restrictions on internet usage.

Victims' families can also be protected from unwanted contact through exclusion zones being set up.

If offenders breach the conditions, the Probation Service can recall them to prison.
