Claim: The Mellows that specializes in doo-wop, which features vocal group harmony to a simple beat with little instrumentation,  was disbanded in  1958, and its lead vocal, Leach Boyd,  gave up singing and went to work in a factory on 134th Street.
Evidence: Lillian Leach (December 20, 1936 – April 26, 2013), also known by her married name, Lillian Leach Boyd, was an American singer who performed lead vocals with the Bronx-based doo-wop group the Mellows. It features vocal group harmony that carries an engaging melodic line to a simple beat with little or no instrumentation. With almost nothing to show for their years of hard work, the group broke up in 1958. Leach gave up singing and went to work in a factory on 134th Street.
