Lauren Laverne presents the last in the series of shows covering the Edinburgh Festival and Fringe. Coming from the Pleasance Courtyard, right in the middle of all the Edinburgh action, the programme will be covering the enormous range of shows and performances that hit Edinburgh in August. Joining Lauren at the Pleasance will be the legendary Joan Rivers. Her autobiographical play, a Work in Progress by a Life in Progress, in which she also appears, is set to be one of the most talked about shows on the Fringe and she remains one of the most entertaining, and occassionally shocking, acts on the circuit. Lauren also meets Matthew Bourne, one of the country's most popular choreographers, his new work Dorian Gray, part of the Edinburgh International Festival, is his first new production in three years. One of the most unusual projects on the Fringe, Scavenger Hunt is also featured on this week's show. Scavenger Hunt is a one off event in which teams solve treasure hunt type clues around the city, producing pieces of art work as they go. The programme will be following many of the teams as they race round the Scottish capital and will feature the exhibition produced at the end of the event. In the last of his Festival reports, Tim Samuels will be speaking to some of the acts that haven't quite hit the headlines and will be asking the performers whether it was worth all the blood, sweat, tears and hard cash needed to put on a show in Edinburgh.
