Joni Mitchell..

At a site today I read that she did three quarters of Crosby Stills Nash and Young (allegedly). I was wondering who was the unlucky one?

Who was the unlucky one? It sounds like Joni Mitchell was.

According to this site (at the top in the blurb for Crosby, Stills, and Nash), Crosby and Nash were two of the three. I can’t find anything anywhere else to back up the notion that she slept with either of the other two, but then my google-fu is lacking before my morning coffee.

This two year old thread

may shed some light (or some hair) on the OP.
