Two world-class harmony singers who had "outgrown" their respective bands - David Crosby and Graham Nash, of The Byrds and The Hollies. Stephen Stills, a refugee from Buffalo Springfield. They debuted at Woodstock and became baby boomer aristocracy. Hit-and-miss: they have their charms - "Our House", "Fair Game", etc., but more often were dull or annoying, rather than exhilarating. Occasional forays onto the purgatory of the Rock Senior Tour, where you can enjoy the purgatory of listening.
