Nash says it had nothing to do with the Hollies, but everything to do with David Crosby and Stephen Stills. He told Spinner.com he knew his time with the Hollies was over when:
I had heard me and David and Stephen sing together. I wanted that golden sound. I craved it. It was beautiful. And the instant that I heard that sound, I knew that I was no longer a Hollie.
Nash says he talks with his former CSN bandmates on a regular basis.
