Exeter Universitys a cappella sensation Semi-Toned return to the Fringe with Sing Theory! Using their trademark combination of vivacious humour, vocal mastery and velvety charm, the 2015 UK Champions and Broadway Baby Bobby Award winners are back to once again prove you dont need instruments to make a fool of yourself in the name of musical entertainment. After three years of sell-out shows, five star reviews and two US tours, Semi-Toned Presents: Sing Theory, is a show bursting with energy, musical variety and flamboyant choreography.
