She's an expert on sauce bottles, remembers the small print on British Rail timetables, and for 30 years she was a regular contestant on Radio 4's Round Britain Quiz. This week on Desert Island Discs, Irene Thomas tells Sue Lawley what she will do with her phenomenal memory now the programme is no longer broadcast. She recalls how she moved from opera singer, to the Black and White Minstrels, before becoming queen of the quiz shows at the age of 41.
