2019 is proving to be yet another busy year out on the road for Graham Nash. Nash spoke to Raleigh's News & Observer and shed light on the status of Crosby, Stills, Nash, & Young -- revealing he's still game to perform with Stephen Stills and Neil Young -- but not David Crosby.

Nash talked about his most recent collection, the 2016 album, This Path Tonight, revealing, "I was on an emotional journey. I was going through a divorce that had to happen. I wasn’t happy in my marriage. And then there was Crosby, Stills & Nash. I wasn’t happy in that situation either."

Nash spoke about this situation between his former bandmates -- who will celebrate their 50th anniversary this year -- with nearly zero chance of a reunion show or tour: "It’s a toxic situation and I don’t do toxic situations anymore. You have to cut that out of your life. I still get along with Stephen (Stills) and I’m still friends with Neil (Young)."

He went on to say, "If Neil came to my house with a song on cassette and he wanted to work with me, I would listen to him. The same goes for Stephen. I want to be around people that make me happy and stimulate me. The lesson with this is that just because you are of a certain age doesn’t mean that you can’t be happy."

Nash recalled the late-'60s scene in Los Angeles, specifically the early period when he was romantically involved with Joni Mitchell: "There were so many reasons that period in Los Angeles, in Laurel Canyon, was such a gas. We were close to recording studios, Hollywood and it was such a free time. It felt like you could try anything. I was constantly moved to write when I was with Joni."

"Our House" from the Crosby, Stills, Nash, & Young's 1970 Deja vu album is regarded as Graham Nash's greatest love song. He discussed its composition, recalling, "A very ordinary thing led to that song being written. Joni and I went to breakfast. We stopped in an antique shop. Joni bought a vase. When we returned home, the song came to life. 'I’ll light the fire while you place the flowers in the vase that you bought today.' Those are the lyrics and it was inspired by a rather ordinary thing that we did."

"Our House" is among the tracks featured on Nash's 2018 career-spanning double-disc collection, Over The Years. The set features a second disc showcasing Nash's personal demos of his best-known tracks taped between 1968 and 1980.

Graham Nash explained why he decided to showcase his warts-and all demos for some of the most expertly crafted pop/rock songs of the era: "But I do realize the value of hearing the demo of 'Our House' and then listening the record of CSN doing it -- CSNY, y'know? The main thing I realized is that I definitely had and idea of how the form of the song would take, and what we did was do our version of my arrangement. When we made the record of 'Our House' we talked about a guitar solo, but it didn't feel like a guitar solo song. And that's how we ended up singing 'la la la' like that -- like a sing-song."
