Crispian St. Peters was an English pop singer-songwriter, best known for his work in the 1960s, particularly hit songs written by duo The Changin' Times, including "The Pied Piper", and Ian & Sylvia's "You Were on My Mind". His popularity waned after he claimed he was a better performer than other well known singers and declared that he was a better songwriter than the Beatles.

Ian & Sylvia were a Canadian folk and country music duo which consisted of Ian and Sylvia Tyson. They began performing together in 1959, married in 1964, and divorced and stopped performing together in 1975.
