On Saturday, the woman with the golden voice, Cerys Matthews, leads a huge sing-a-long of family songs at the Clore Ballroom in the Southbank Centre. We listen to Cerys’ 6Music show every Sunday, so we can’t wait for our kids to freak out in recognition when she starts talking at this music-from-around-the-world gathering. It’s going to be warm and inclusive, and Cerys’ mellifluous voice will charm the pants off everyone. Cerys’ book, A Sing-a-long Book: Childhood Songs for Long Car Journeys and Rainy Days is due out in June. Free. Saturday, 3pm. More here
