I was never convinced that Crosby added that much to the group, his history with the Byrds notwithstanding. His “success” seems to be from standing in the shadow of truly talented musicians like Roger McGuinn, Graham Nash, and Steve Stills. Check out “Treetop Flyer” and then look for any solo performance by this fatheat that comes anywhere close.
90% of CSN&Y was Stills.
You got that right.
