London, Aug 22 : Gary Glitter, the 1970s glam rocker and convicted paedophile, indicated his lust for under-age sex during an appearance on 'This Is Your Life'.
Glitter starred on the ITV series' profiles in 1991 - six years before his arrest over child porn on his laptop.
In the episode, a jokey reference to 'adolescent schoolgirls' in uniform prompted him to put his finger to his lips. He could also be clearly seen mouthing 'shush'.
The gesture and the whispered 'shush' were directed at actress and children's writer Tessa Dahl.
Hosted by Michael Aspel, millions of ignorant fans were watching the programme without realising the significance.
Dahl was recalling a time in the 1980s when broke Glitter was living at the home she shared with her teenage sister Lucy.
She said Lucy 'used to pack the house with her adolescent schoolfriends in school uniforms.
"They would skive off school and she would bring them to the house and charge them pounds to gaze at Glitter," The Sun quoted Dahl, as saying.
However, as Tessa, mum of model Sophie and daughter of kids' book author Roald, mentioned schoolgirls in uniform, grinning Glitter made the gesture.
