Last night it had its first full performance in the UK since 1980. It's already in Wkipedia:
The work was performed at the Proms on 17 July 2011 under Martyn Brabbins, with Susan Gritton soprano, Christine Rice mezzo-soprano, Peter Auty tenor, Alastair Miles bass, City of Birmingham Symphony Orchestra Youth Chorus, Eltham College Boys' Choir, Southend Boys' and Girls' Choirs, Bach Choir, BBC National Chorus of Wales, Brighton Festival Chorus, Côr Caerdydd, Huddersfield Choral Society, London Symphony Chorus, BBC Concert Orchestra and the BBC National Orchestra of Wales. The performance sold out on the first day of ticket sales. It was enthusiastically received by the audience, with noisy applause (even by Proms standards) lasting several minutes.
