Graham Nash is one of the most durable and prominent supporting figures in rock music history. As a harmony singer and sometime lead singer with the Hollies and Crosby, Stills, Nash, and Young, his voice is among the most familiar in two distinct eras and schools of rock music. He has since gone on to a productive if usually unexceptional career as a singer/songwriter, both as a solo artist and, more often, in collaboration with David Crosby. He has also reunited periodically with Crosby and Stephen Stills and, more rarely, with Neil Young, and the occasional project with the Hollies.Graham Nash's musical future was determined on the day in 1947 when he met Allan Clarke, the new boy in his class at the Ordsall Primary School. They became friends, and it turned out that one of the interests that they shared was music. They both sang in choir, and discovered that their voices complimented each other very well. Unfortunately, there was no such thing as rock & roll at the time, and their spontaneous musical efforts together didn't begin until the 1950s.
