Clarke produced the album, and afterwards continued working with the band. Sometimes known to fans as "The Sixth Moodie", he produced their albums and singles for the next eleven years. Engineer Derek Varnals also contributed heavily to the creation of the early Moody's studio sound, working with Pinder and Clarke to create a more symphonic overlapping sound on the mellotron as opposed to the sharp 'cut off' the instrument normally gave, partly achieved by removing all the "sound effects" tapes (trains, whistles, cockerel crowing, etc.) and then 'doubling up' the tapes of orchestral instruments' sounds, which combined with Pinder's ability and sensitivity at playing (Pinder having earlier worked for the company that manufactured the mellotron) and Varnals' recording skills at creating an orchestral 'wave' sound that characterised their non-orchestra accompanied sound thereafter.
