Besides the Beatles, Martin worked with other recording artists, including Shirley Bassey, Bernard Cribbins, America, Kenny Rogers, the trio EL&P, Dudley Moore, and Little River Band. He wrote a book, "All You Need is Ears", that told his life story and explained how many of his most famous recordings were made. During the 1990s, Martin was made a knight by the British government, for his work and his role in popular music.
