What is the real name of the person who wrote the music for the hit songs "What Now My Love", "It Must Be Him", "The Day That The Rains Came Down" and "Let it be Me"?

François Gilbert Léopold Silly AKA Gilbert Bécaud

Yes, excellent answer. I saw him on stage four times and he was a true artist. He had a hit record in the UK once too, but singing in English just did not work for him. He was a "performer" of his songs,, and in French he really did the business. I was upset when he died.
