John Peel appeared in one episode of the Saturday morning ITV children's programme Tiswas, in the course of which he was splashed with gunge in a cage with other guests. He also played an art critic on the show.
“John was a big fan so I said ‘Come on it, then’. He wondered what he could do and, in the end, for this hilarious contrast, we had myself, Chris Tarrant and John having this conversation about life – apparently oblivious to the havoc being caused by the Phantom Flan Flinger, who was attacking the audience at the same time. We just carried on talking!”
