Front Row - Highlights from the Edinburgh Fringe

As the 64th Edinburgh Fringe Festival reaches its halfway stage, Mark Lawson presents a taste of the acts making waves and clocking up five-star reviews. Before a live audience, Tim Vine - master of the single-line gag - attempts to get to grips with our fascination for good old-fashioned corny jokes. Former stand-up and classical pianist Rainer Hersch offers his tribute to the late Danish comic and acclaimed pianist Victor Borge. Eugene Pack and James Lance wonder at the sheer lack of self-awareness of the celebrity autobiographers from Mr T and Eminem to Tiger Woods and Katie Price. And actress Mercy Ojelade describes playing the protagonist of the play that's attracting a great deal of attention - Roadkill - which takes the tiny audience on a trip to a secret location in Edinburgh to tell the true life story of a girl sex-trafficked from Nigeria to Scotland. And if the spoken word is not your thing, The Boy With Tape On His Face presents a whole hour of stand-up comedy without uttering a sound. Producer Jerome Weatherald.
