Clutching her walking stick, 80 year-old Audrey Federa from Worthing, scuttles to the front of the small Italianate-style church in Brighton, and starts girating energetically. An electric set by virtuoso Senegalese kora player, Seckou Keita, is approaching its end and Keita has invited the capacity audience to dance. Most of them do. “I don’t know what came over me” said Audrey catching her breath after the show. “The music just lifted me to my feet and I felt I had to dance.”
