Brewer & Shipley are an American folk rock duo, consisting of Michael Brewer and Tom Shipley, who rose to prominence in the late 1960s and early 1970s. Their music is marked by tight harmonies, introspective lyrics, and a blend of folk, rock, and country influences. They are best known for their hit single "One Toke Over the Line," which was a counterculture anthem in the era of its release in 1970. Despite controversy surrounding the song's drug references, its success solidified Brewer & Shipley's place in music history.
