David Crosby from The Byrds and Crosby, Stills, Nash & Young has passed away

Singer-songwriter David Crosby, a founding member of two popular and enormously influential ’60s rock units, the Byrds and Crosby, Stills, Nash & Young, has died.

He was 81 years old.

His wife announced the sad news in a statement, writing: "It is with great sadness after a long illness, that our beloved David (Croz) Crosby has passed away.

"He was lovingly surrounded by his wife and soulmate Jan and son Django. Although he is no longer here with us, his humanity and kind soul will continue to guide and inspire us. His legacy will continue to live on through his legendary music."

She continued: "Peace, love, and harmony to all who knew David and those he touched. We will miss him dearly. At this time, we respectfully and kindly ask for privacy as we grieve and try to deal with our profound loss. Thank you for the love and prayers."

With bandmates Roger McGuinn, Gene Clark, Chris Hillman and Michael Clarke, Crosby rose to fame in the 60s as a singer and guitarist for the Los Angeles-based folk-rock band The Byrds.

He spent four years with the group, singing on its many hits including the chart-topping covers 'Mr. Tambourine Man' and 'Turn! Turn! Turn!'

Later bonding with Stephen Stills and Neil Young of Buffalo Springfield and Graham Nash of the Hollies, Crosby launched Crosby, Stills, Nash & Young.

He was inducted into the Rock and Roll Hall of Fame twice, as a member of the Byrds (1991) and Crosby, Stills & Nash (1997).

Crosby is survived by his wife Jan Dance, their son Django, son James Raymond and two daughters, Erika and Donovan, from previous relationships.

In 2000, it was revealed by singer Melissa Etheridge that Crosby was the biological father of two children born to Etheridge’s then-partner Julie Cypher via artificial insemination.
