Graham Nash has spent the last 4 years, on and off, working on this 40 song collection of live Crosby, Stills, Nash, and Young hits, taken from their 1974 tour, 40 years ago.
The set comes in many formats, LP, CD, MP3, Blue-Ray, and even a Starbucks edition. And the ultimate collection set comes with a 188 page booklet, full of photos of the band from the tour.
A true labor of love for "history" as Graham told us.
