In 1977, he worked on the "Life" album for the veteran Jamaican-born soul singer Jimmy James, which put out two chart hits "I'll Go Where your Music Takes Me" and "Disco Fever". In early 1978, Biddu's own "Journey to the Moon" was a hit, peaking at No. 41 in the UK. That same year, he scored the music for the English film "The Stud", starring Joan Collins; the film's soundtrack was successful on the UK Albums Chart, where it reached No. 2. He also produced the soundtrack for its sequel, "The Bitch", in 1979. During the late 1970s, Biddu also had a hit in France with Claude François, for whom he produced the song "Laisse Une Chance A Notre Amour", a re-working of Jimmy James UK hit song, "Now Is the Time".
