Listen to the Irish folk song, "Those were the days my friend, I thought they'd never end, we'd live and die forever and a day - we lived the life we choose, we'd fight and never lose, those were the days, oh yes, those were the days" This is almost exactly patterned on that song.
Nice! The "Wild Tales" release is just Crosby on backing vocals; Stills's added harmonies make a great song even better. (Obv. they had Stills singing in concert, but that audio doesn't compare to this. Thanks again.)
