Perhaps it's the heat, or the Cuban rum, or maybe it's just creeping middle-age but strange things are happening to TV's best-known gang of Geordie brickies. Neville, for instance, has turned into Newcastle's version of ""Our Man in Havana"", furtively sneaking around the place muttering the name of Heather to everyone in the hope of finding his ""contact"" in the British Embassy. Meanwhile Oz is giving flowers to a beautiful Cuban prima ballerina, and dear Barry is still having therapy by mobile phone.
