Ida Barr used to be a music hall star, but she’s been retired for quite some time. She has begun supplementing her pension by updating her skills and passing them on to young people. She’s dug out her old costume and is teaching rap. She calls it artificial hip hop and makes rhymes about the things that concern her – Gaviscon, flu jabs and a fall she had doing the hokey cokey last Diwali. Her style has been described as the Angina Monologues. Listen to the report at Radio 4.
