Jocelyn was one of eleven of Britain’s renowned film composers commissioned to write music for the Thames Diamond Jubilee Pageant in honour of the Diamond Jubilee of Elizabeth II. Jocelyn created a new movement using Handel’s Water Music for inspiration. The suite of music was performed for the first time on 3 June 2012 by an ensemble of live musicians on musical barges carrying choirs and orchestras, part of a pageant of 670 military, commercial and pleasure boats on the river Thames.
