Grammy-award winning composer Nile Rodgers treated commuters at London’s South Bank to an impromptu live performance early this morning to celebrate the new Sky Arts. Nile, disguised as an ordinary busker, pitched up to perform whilst commuters hurried through the morning rush hour. Nile performed his impromptu gig to mark the relaunch of Sky Arts as a single superchannel, alongside Sky Arts On Demand, which contains over 1,000 of arts programming.
