Despite a very busy schedule, Charles occasionally manages to find time to do a little composing. Some of his work is on the album Extempore II (2003; see discography). More recently, he has completed Purcell's anthem Arise My Muse, which the composer left unfinished at his death. The world premiere performance of this piece took place at the Montreal Baroque Festival on 27 June 2009.
The baroque oboist Bruce Haynes, husband of Susie Napper of the Montreal Baroque Festival, sadly died on 17 May 2011 at the age of 69. Susie took the courageous decision to continue with the Festival, and Charles composed a two-part madrigal in his memory which was performed during the Festival by the Gesualdo Consort of Amsterdam, led by Harry van der Kamp. The Charles Daniels Society extends its heartfelt sympathy to Susie.
