The producer of a comedy sketch from 1980 which shows children being abducted and put into a van bound for a show hosted by Rolf Harris has said it makes his “blood run cold”.

BBC producer John Lloyd said it felt “awful” to look back at the clip which was shared on YouTube this week in the wake of Harris’s sex abuse conviction, according to report by The Independent.

The sketch, written by Lloyd, shows actors like Rowan Atkinson snatching children from the street and putting them into a truck adorned with the name of Harris’s children’s program, “Rolf on Saturday OK?”.

Mr Lloyd said that it a “pathetically mild” joke about how they “had to drum up the audience for a terrible Saturday show”.

The video clip was from the satirical show ‘Not The Nine O’Clock News’, which was written and co-produced by Mr Lloyd.

“It makes the blood run cold to watch it now thinking about what he had done,” said Mr Lloyd.

The internet was also aghast this week when a video of Rolf Harris emerged of him singing a cover of the Divinyls’ “I touch myself”.

Rolf Harris was jailed last week for 5 years and 9 months following a guilty verdict of 12 counts of sex abuse.
