OVER HERE does for Great Britain what Alistair Cooke has done for the States. Raymond Seitz was US Ambassador to Britain from 1990 to 1994. Unlike the majority of his predecessors he didn't return home, but decided to stay on in the UK. Again, unlike the majority of US Ambassadors, Seitz was not a political appointment, but a career diplomat - and one of the most successful of his generation. Following on from his successful radio 4 series of the same title, OVER HERE, is about the Transatlantic relationship at every level : Politics, diplomacy, education, language, sports, animals, currency, pomp and circumstance.
