Celebrity Britain by Barge: Then & Now S01E05 - Episode 5

Bill Oddie, Jennie Bond, Anne Diamond and Pete Waterman head to Northamptonshire to navigate the mighty Grand Union Canal, at one time the busiest waterway on the network and the vital transport link between Birmingham and London. Travelling from north of Milton Keynes to the old canal port of Braunston, they celebrate the `boat people", who once lived and worked on Britain's canals, keen to uncover the secrets of this lost community. Travelling through a notoriously dark and deadly tunnel at Weedon Bec, they also visit a once secret arms store.
