British musician Graham Nash is seen after performing for a satellite radio show to promote his new retrospective boxed set in New York January 29, 2009. Nash, the English guy in the rock supergroup Crosby, Stills & Nash, is back in the studio working on the first CSN album in a decade and has just released a three-disc box-set of his work. The writer of rock classics such as "Teach Your Children" and "Our House," grew up in Manchester, in post-war England. Inspired by rock 'n roll stars like Buddy Holly and the Everly Brothers, he formed The Hollies, which had several hits and was a part of the "British Invasion" of America. But he found his true calling when he teamed with David Crosby and Stephen Stills in Los Angeles to write and perform some of the songs that defined the Woodstock era of social upheaval of the late 1960's and 70's.
