Also in 1971, Budd was asked by Nelson to compose the music to "Flight of the Doves", and worked with Dana who sang the film's theme; and composed the scores for the adventure "Kidnapped" and the western "Catlow". In 1972 he recorded the score to "Fear Is the Key", which was based on the Alistair MacLean novel. Whilst recording the score, Budd was influenced by Ronnie Scott, Tubby Hayes and Kenny Baker, thus giving the music a jazz-sounding theme. Scott played the saxophone for the car chase sequence.
