Wow.  I can't believe nobody has commented on this.  What a gorgeous song; enormous potential.  I like this best of all so far.  I'm very impressed.  You're a very nostalgic person with a deep sensitivity to the human condition and what we humans always look to when we wonder about our existence.  You're a precious human being bro; I think this vein of philosophical perspective is the most powerful there is; stay with it and keep pushing forward regardless of what the world outside delivers.  You already have a grip on whats important; expand on it.  Love this.
