 Both of these tracks feature Neil Young, who does not appear on any track on this set.Although "Our House", "Teach Your Children", and "Carry On" are on the "Crosby, Stills, Nash, and Young" album "Déjà Vu", Young was not involved in those songs, allowing "Greatest Hits" to authentically be considered specifically a "Crosby, Stills & Nash" collection.The selections derive from the group's first four studio albums ("Crosby, Stills & Nash", Déjà Vu", "CSN", "Daylight Again)", but nothing from their last four ("American Dream", "Live It Up", "After the Storm", and "Looking Forward").
