Presented by Jenni Murray. Around 20,000 people are expected to attend the 30th WOMAD festival in Wiltshire this weekend. WOMAD - World of Music, Arts and Dance - was founded by singer Peter Gabriel, and part of its success is due to the work of three women. We're joined by two of them, festival programmer, Paula Henderson, and Annie Menter who's the director of the WOMAD foundation, to explain the event's continuing success. The economic crisis in Greece has led to an increase in prostitution and now sex workers are being blamed for a rise in HIV infection rates. Some prostitutes have been rounded up by the police and demonised in the press. What happens when you are a grandparent and you have two or three sets of grand children living in different parts of the country? How do you share out your resources fairly and if you refuse to do long-distance caring, how best to handle any family fallout? The UK's first female accredited beer sommelier is Sophie Atherton. She joins Jenni to explain how to make the best beer.
