I am no believer in historical determinism, nor am I a Scottish (or any other kind of) nationalist, but the fact that The Sixteen should commission James MacMillan to set anew the text used by Robert Carver in his 19-part motet O bone Jesu brings a profound satisfaction. No one else could have tidied up five-centuries-old loose ends as he. Carver (c. 1487–1566) was part of the dizzyingly rich flourishing of Scottish culture in the early years of the 16th century – a Catholic culture, doused by the dour sincerity of the Reformation (the MacTaliban, if you wish). MacMillan, a dry-eyed member of Scotland's Catholic minority, is the first composer since those days whose combination of faith and accomplishment allows him to pick up the glove torn from Carver's hand. His O bone Jesu – given its first public airing by The Sixteen under their founder-conductor Harry Chistophers at Southwark Cathedral on 10 October, at the outset of a year-long tour that takes them round the British Isles and to North America – may not quite reach Carver's Olympian heights (no other Scottish composer has achieved commensurate greatness) but it exploits a striking range of emotional reference nonetheless.
