 Established recording artists such as Marty Robbins ("Ribbon of Darkness"), Leroy Van Dyke ("I'm Not Saying"), Judy Collins ("Early Morning Rain"), Richie Havens and Spyder Turner ("I Can't Make It Anymore"), and The Kingston Trio ("Early Morning Rain") all achieved chart success with Gordon Lightfoot's material.In 1965, Lightfoot signed a management contract with Albert Grossman, who also represented many prominent American folk performers, and signed a recording contract with United Artists who released his version of "I'm Not Sayin'" as a single.Appearances at the Newport Folk Festival, "The Tonight Show Starring Johnny Carson", and New York's Town Hall increased his following and bolstered his reputation.
