Since their formation in the late 60s, Graham Nash has been an integral part of the various incarnations of groups bearing his name: Crosby, Stills, Nash; Crosby, Stills, Nash and Young; and Crosby and Nash - not to mention his solo efforts from time to time. But prior to the supergroup known as CSN and its legendary spin-offs, Nash was also an integral part and founding member of The Hollies.
Formed in the early 60s, the group charted their first tune in Britain in 1963 and their first American album the following year. The British music media often dubbed them "the third group" after the Beatles and the Stones and in the early days they recorded "made-to-order" songs written by such folks as Graham Gouldman, later of 10CC. Between 1963 and 1969 the Hollies placed a phenomenal 20 hits into Britain's Top 40, many of them co-written by Nash, along with band-mates Allan Clarke and Tony Hicks.
Of course, Nash left the Hollies in 1968, met up with David Crosby and Stephen Stills and the rest is musical history. Before he departed he co-wrote his last Hollies' tune, one of the most popular in their songbook to date.
