ok, life is tough, we are less and less naivé, but if you have an open heart and an open mind, this is the best movie that you will ever see! i first saw it in arizona on a hot summer's night in 1973. i have seen it again and again. donovan was right for the score. this is a timeless, ageless tribute to the value and joys of love!
