Cross-cultural saga 'Brixton Beach', by Roma Tearne

She's duetted with Cee Lo Green and opened for Prince and she's only just getting started - we meet singer Selah Sue. Plus, we go to the Jazzitudes music festival in the north of France. And a family torn apart by civil war: writer and artist Roma Tearne joins us in the studio to talk about her fabulous book, "Brixton Beach".
