The centenary was also marked by two new musical compositions. The 40-minute oratorio "Eventide: In Memoriam Edith Cavell" by Patrick Hawes premiered in Norwich Cathedral in July 2014 and had its London premiere in St Clement Danes, The Strand, London on 12 October 2015, the exact centenary of her death. The Belgian Edith Cavell Commemoration Group also commissioned a 20-minute-long setting of the Latin Mass by David Mitchell for the centenary - it premiered in Holy Trinity Pro-Cathedral, Brussels on 10 October 2015, in the same choir stalls where Cavell sang in 1915, with Haydn's "Missa in Angustiis" also performed at the same concert.
