Willcocks made recordings with the (London) Bach Choir, the English Chamber Orchestra, the Academy of St Martin in the Fields, the Jacques Orchestra, the Philharmonia Orchestra, and the London Symphony Orchestra as well as with the Choir of King's College, Cambridge, with whom he regularly conducted the Nine Lessons and Carols service on Christmas Eve, broadcast by the BBC every year since 1931. With The Bach Choir, in particular he recorded works by Johann Sebastian Bach, especially his motets and, sung in English, his St John Passion and a stately rendition of the St Matthew Passion, a piece he regularly conducted for broadcast Easter performances. He also served as general editor of the Church Music series of the Oxford University Press. During his years at King's, an early and frequently reissued recording of the Allegri "Miserere" was made in March 1963 by the choir, conducted by David Willcocks, and featuring a 12-year old Roy Goodman, later a distinguished conductor, as the treble soloist. In 1965, he made his famous recording, with the Choir of King's College, of Tallis's Spem in alium.
