Members of the Royal School of Church Music's new Millennium Youth Choir stage a concert in Merton College Chapel on Monday. The singers, aged from 16 to 23, will perform a wide selection of music including Victoria's Magnificat Primi Toni and Scarlatti's Stabat Mater. The choir, formed last year at the suggestion of the Archbishop of Canterbury, will broadcast Choral Evensong live for Radio 3 on Wednesday.
