William Petter was Director of Music from 2011 until his death in 2016, having been a founder member of the Choir of St Magnus the Martyr in 2005. He was succeeded by Lottie Bagnall. The choir issued CDs in 2013 ("Regina Coeli") and 2014 ("Inexplicable Splendour"). St Magnus's organist, John Eady, has won composition competitions for new choral works at St Paul's Cathedral (a setting of "Veni Sancte Spiritus" first performed on 27 May 2012) and at Lincoln Cathedral (a setting of the Matin responsory for Advent first performed on 30 November 2013). David Pearson specially composed two new pieces, the Communion anthem "A Mhànais mo rùin" (O Magnus of my love) and a hymn to St Magnus, "Nobilis, humilis", for performance at the church on the feast of St Magnus the Martyr on 16 April 2012.
