 Welcome back to the Arts Hour on the BBC World Service with me, Nicky Bady. And if you've only just joined us, there's so much that you missed in the first half of the show. The American musician Questlove remembering the first time he heard Rapper's Delight. British novelist Zadie Smith described an inspirational trip to West Africa. And actors Viggo Mortensen and Vicky Creeps discussed their Western. If you missed any of that, you can catch up by the BBC Arts Hour web page. MUSIC
