The BBC World Service celebrated its seventieth birthday this weekend with five concerts around the world – the events in Dakar, Mumbai, Kabul, Mexico City and London featuring musical talent from around the world including Youssou N'Dour, Baaba Maal and Ms Dynamite.
In what was a real technical challenge all five concerts were broadcast on the Service in a programme fronted by Radio 1 DJs John Peel and Emma B in London.
