ITV series Tiswas, its host Chris Tarrant has revealed. Rick and bandmate Francis Rossi were among a host of showbiz stars packed into a “celebrity cage”.Chris, 75, said: “All of a sudden, the unmistakable smell of marijuana came wafting into my nostrils from the direction of the cage.“Here’s me, the producer of a supposed children’s television programme, kids everywhere, parents everywhere, journalists everywhere, and one of my guests is smoking a joint.“I abandoned the sketch, much to Lenny Henry’s bewilderment, and rushed to the cage, completely drenching everyone in it with bucket after bucket of the Midland Water Board’s finest product.
