McCallum did not sing on these records, as many television stars of the 1960s did when offered recording contracts. As a classically trained musician, he conceived a blend of oboe, English horn, and strings with guitar and drums, and presented instrumental interpretations of hits of the day. The official arranger on the albums was H. B. Barnum. However, McCallum conducted, and contributed several original compositions of his own, over the course of four LPs. The first two, Music...A Part Of Me and Music...A Bit More Of Me, have been issued together on CD on the Zonophone label. On Open Channel D, McCallum did sing on the first four tracks, "Communication", "House On Breckenridge Lane", "In The Garden, Under The Tree" (the theme song from the movie Three Bites Of The Apple), and "My Carousel". The music tracks are the same as the Zonophone CD. This CD was released on the Rev-Ola label. The single release of "Communication" reached No. 32 in the UK Singles Chart in April 1966.
