CSN&Y recorded a CD that was released as a VH1 broacast. While talking about the good old days, either Stills or Crosby says (and I paraphrase): "We recorded about 760 songs together" and I think Nash then chimes in: "...and Neil wrote about 600 of them"
This guys a monster song writer, blessed with a vocie more a kin to Dylan than CS or N, Young contionues to put out fine and challenging music.
