It's probably from the 1960s.

Peter Cook is sat talking to a theatre audience and singles one person out to tell him that he knows that he will be knocked down by a bus. Hiding in the theatre won't help...

I thought it was from Beyond The Fringe, but it doesn't appear to be from any recording I have.

Does anyone on here remember or know where the sketch can be found?

Many thanks.

I don't remember, but this does ring a bell and now I'm intrigued. Following this to see if anyone knows!

Did he have a hat and a grey-brown coat on? If so, it was an E L Wisty sketch. As it was televised it might be Secret Policeman, I don't think the Behind The Fridge tour and as you said it's not Beyond The Fringe.

That could be it. Thanks.
