Glenn Robertson Yarbrough was an American folk singer and guitarist. He was the lead singer (tenor) with the Limeliters from 1959 to 1963 and also had a prolific solo career. Yarbrough had a restlessness and dissatisfaction with the music industry which led him to question his priorities, later focusing on sailing and the setting up of a school for orphans.

The Limeliters are an American folk music group, formed in July 1959 by Lou Gottlieb, Alex Hassilev (banjo/baritone), and Glenn Yarbrough (guitar/tenor). The group was active from 1959 until 1965, and then after a hiatus of sixteen years, Yarbrough, Hassilev, and Gottlieb reunited and began performing again as The Limeliters in reunion tours. On a regular basis a continuation of The Limeliters group is still active and performing. Gottlieb died in 1996, Yarbrough died in 2016, and Hassilev died in 2024, the last founding member, who had remained active in the group, retired in 2006, leaving the group to carry on without any of the original members.
