Graham Nash has married 40-year-old artist/writer Amy Grantham. In 2016, Nash -- who's now 77 -- divorced his second wife of 38 years, Susan Sennett. The couple has three adult children and several grandchildren. Nash had been briefly married in the 1960's to first wife Rose Eccles.

Nash, who in recent years has relocated to New York City, spoke to The Daily Mail and gave the back story on the nuptials, revealing the couple married both in Woodstock, New York and in the Scottish Highlands -- a favorite vacation spot for Grantham where they partook "in a pagan 'handfasting' ritual," explaining, "Amy is from Tallahassee in Florida, but she's loved Scotland for about the last 15 years and she's gone there every year. She introduced me to the Scottish Highlands, which I'm ashamed to say I'd never been to, and it is the most beautiful country in the world. We had a special ceremony in the Highlands and then a couple of weeks later we got married legally because the handfasting -- which has been going on for a thousand years in Scotland -- is not a legal wedding. Romantic? Absolutely. Legal? Not. So to be able to protect Amy from the slings and arrows of outrageous fortune, we decided we'd get legally married in a very small ceremony in Woodstock."

Nash's relationship with Grantham coincided with the collapse of Crosby, Stills, & Nash -- a situation Nash told us is far more liberating than heartbreaking: "It's phenomenally freeing. 'Cause, y'know, when you're in a band with David (Crosby), and Stephen (Stills), and Neil (Young), y'know, a lot of decisions have to be made and somebody likes something and somebody doesn't like something, and you wanna know, 'Can I sing this song? I've got a brand new song I wanna sing -- do you mind?' I don't have to ask any of those questions. I'm concentrating on me. I concentrated on Crosby, Stills, Nash, & Young for 45, 50 years -- and now it's different."

Graham Nash will next perform on July 11th in Gavorrano, Italy.
