Peter and Gordon were a British pop duo, composed of Peter Asher and Gordon Waller, that achieved international fame in the 1960s. Known for their harmonious, melodic style, they became one of the most successful acts during the British Invasion of the U.S. music scene. Their signature sound was marked by the hit "A World Without Love", a song written by Paul McCartney of The Beatles, which topped both UK and US charts. Despite their relatively short career, their music had a significant influence on the folk-pop genre.
