Maddocks' parents were enthusiastic amateur musicians and, by the age of 14, Anne was playing the organ for services at two village churches.
She had perfect pitch and as Hawkins put it, she played Widor's music "with the master's interpretation".
She gave the first British performance of Poulenc's Organ Concerto in Chichester Cathedral in 1943.
She was married to Morris Maddocks, then curate of St Peter's Church, Ealing and later Assistant Bishop of Bath and Wells, in Chichester Cathedral in 1955.
Anne died in October 2006 and her funeral was in Chichester Cathedral, where Charles Widor's Mass was sung.
