2413 This subset of Crosby, Stills, Nash & Young featured David Crosby (b.Aug 14, 1941) and Graham Nash (b.Feb 2, 1942) relying on their sweet harmonies and strong songwriting. The duo lasted from 1972 to the more-or-less permanent re-forming of Crosby, Stills & Nash in 1977. ~ William Ruhlmann, All Music Guide 1909
