Judy Collins is an American singer-songwriter born in 1939 who became a prominent folk music figure in the 1960s and beyond. She is known for her distinctive soprano voice and her interpretations of both traditional folk songs and contemporary compositions, achieving commercial success with hits like "Both Sides Now" and "Send in the Clowns." "Sweet Judy Blue Eyes" is a Stephen Stills composition written about Collins, and while often associated with her, it was famously performed by Crosby, Stills & Nash.
