It is so ordinary, so everyday, that a huge range of idioms, traditions and beliefs in the power of sweeping have appeared. Award-winning poet, Imtiaz Dharker presents a reflective evocation in words, sound and music of the broom in many cultures.

Trevor Reekie hosts a weekly music programme celebrating an eclectic mix of 'world' music, fusion and folk roots. Tonight, an interview with Christopher C. King, a Grammy-award winning producer and audio engineer, and a musicologist. But it's his avid passion for collecting old 78 rpm records that has established his reputation. Profiles of King have appeared in the New York Times Magazine and Washington Post.
