And just to prove that you just can't get enough of Grainne Seoige on British TV, here she Is on this new show in which Adrian 'Vyvyan' Edmondson investigates the National Grid. Grainne herself tackles the problem of overcrowded trains and Stephen K Amos tries to make milkmen a common sight once more. Stanley Johnson finds more good Samaritans from the general public, the worst roadworks in Britain are revealed and the programme celebrates the people who ensure cashpoints always contain money. Following at 8.30pm is more BBC hilarity in the form of The Impressions Show with Culshaw and Stephenson, including Ross Kemp taking on his most dangerous mission ever, Jimmy Carr turning up unexpectedly at a funeral, and Davina McCall getting in a right mess.
