Crosby is the sperm donor for Melissa Etheridge and Julie Cypher's 2 children, who were born through artificial insemination.
CSN was formed from what was left of three prominent 1960s groups: The Byrds (David Crosby), Buffalo Springfield (Stephen Stills) and The Hollies (Graham Nash). After the release of the band's first album in 1969, another Buffalo Springfield alum, Neil Young, joined the band.
Crosby has gone through many drug problems, causing a series of operations. Even he admits that he's lucky to be alive.
Their first greatest hits collection featured artwork by Joni Mitchell, whose first album was produced by Crosby.
They performed at both the original and the second Woodstock. Their performance at the original Woodstock was only their third show together. They had a few more under their belts the second time around.
Jimi Hendrix taught Stills how to play lead guitar.
They are the only group to top the charts with three consecutive LPs where one was a studio album (Deja Vu), one was a live album (4 Way Street), and one was a greatest hits album (So Far).
Stills got into a fistfight with an audience member at a festival in Big Sur, California that was being filmed as a showcase for good vibes.
In the group's various configurations and as solo artists they have collectively released nearly 100 albums.
Each band member has been inducted twice into the Rock And Roll Hall Of Fame.
The group was somewhat unique in that each of the members were recording solo albums at the height of their success as a group. Other configurations included Crosby Nash (they made 8 albums together) and the Stills-Young Band, which made one album in 1976.
The group was successful from the start, beginning with their first album and continuing through the early 1970s. CSNY was one of the few groups selling as many albums as the Beatles.
Young left the group in 1976, returning long enough to record an album in 1988 after Crosby finished a jail term on drug and weapons charges, fulfilling a promise Young had made to record with CSN if Crosby could beat his drug addiction.
Stephen Stills underwent successful surgery for prostate cancer on January 3, 2008, which was his 63rd birthday. (thanks, Bertrand - Paris, France, for above 6)
