Lee Hays (March 14, 1914 – August 26, 1981) was an American folk-singer and songwriter, best known for singing bass with the Weavers. Throughout his life, he was concerned with overcoming racism, inequality, and violence in society. He wrote or co-wrote "Wasn't That a Time?", "If I Had a Hammer", and "Kisses Sweeter than Wine", which became Weavers' staples. He also familiarized audiences with songs of the 1930s labor movement, such as "We Shall Not Be Moved".
