While with D'Oyly Carte Walker continued to produce some of the company's Decca recordings. During the same period as a conductor he directed a series of popular classical pieces recorded by Decca crews for Reader's Digest's record label in 1962. This was followed in 1963 by a three disc set of excerpts from the Savoy operas also for Reader's Digest with D'Oyly Carte principals singing for contractual reasons roles that they did not normally sing on stage. These recordings were produced by Charles Gerhardt. In 1964 Walker conducted the D'Oyly Carte company and the Royal Philharmonic Orchestra in a soundtrack recording for an animated film of Ruddigore by Halas and Batchelor. In the same year Walker married Angela Lang a member of the D'Oyly Carte company's office staff.
