From Roman soldiers' marching songs to Elizabethan madrigals with the naughty words discreetly veiled by hey-nonny-nonnies, and from the saucy repertoire of 18th-century catch clubs to today's explicit popular music, Lucie Skeaping - who has performed a few bawdy ballads in her time - presents a history of sex in music. Is song only really sexy when it's reacting to highbrow, moralistic taste? And will today's sexual openness in western music be followed by a period Of prudishness? Producer Andrew Green

Seven years ago, British Army corporal Dave Vaatstra and his fellow soldiers were sent as UN Peacekeepers to the war in Bosnia to the so-called "safe area" of Gorazde, a sister town to Srebrenica. In May 1995, the Serbs attacked Gorazde in an assault never made public at the time, snatching 33 British hostages and threatening to take the town itself. It was a national crisis and came as widespread hostage-taking in Bosnia brought the whole UN mission to collapse.
Cpl Vaatstra tells how men from his battalion, the Royal Welch Fusiliers, fought to save the town. Reported and compiled by Gillian Sandford , this is a tale from the trenches told by the men who were there. Producer Mark Smalley

Bruce Clark asks whether a Union that was losing members as well as gaining them could survive, and whether the European juggernaut can stay on the road.
