Cardinal Vaughan Schola Cantorum on Instagram: "Malakai Bayoh singing in last night’s concert with Sigur Ros at the Royal Albert Hall. Sigur Ros lead singer Jonsi would welcome Malakai to the stage with a shake of hands and then leave him to deliver his solo to end the first half of the concert. This act of humility was typical of the incredibly kind, generous way that these wonderful musicians welcomed us into their extraordinary musical world this week."
