Documentary: Gone To Pot: American Road Trip, 9pm, ITV

Here we have a travel show featuring three ageing actors, a retired darts player and an ex-England footballer. As if that was not obscure enough, they are in America to explore the pros and cons of legalising marijuana. Anyway, we cannot help but want to tune in to see what John Fashanu, Pam St Clement, Christopher Biggins, Bobby George and Linda Robson (all above) learn about the subject.
