Although the tradition of the Anglican Church was his cornerstone, Ledger could be ecumenical in his outlook. He composed The Dominican Mass for an American Roman Catholic church, a setting based on a new translation of the Roman Missal that includes congregational singing; and, in 1974, signed a joint letter with other musicians to a newspaper expressing concern about the possible dissolution of the choir of Westminster Cathedral. In his performing it would be easy to categorise Ledger as an early music specialist – and indeed his six appearances at the BBC Proms between 1964 and 1972 featured music by Bach, Handel, Purcell and Vivaldi. Yet there were fine accounts of him accompanying Robert Tear in Schubert’s Die Winterreise at the Queen Elizabeth Hall in 1981 (also recorded on the ASV label), and Fauré’s Requiem with Dame Janet Baker on EMI.
