My buddy Robert sent me this a couple of weeks ago. It certainly sounds like it was released in 1968, which it was. Notice the sitar. A lovely and sad song. I don't recall ever hearing anything by David Blue back in those days, though the cover of this album looks familiar. It seems he was a friend of Dylan's. And his real name was David Cohen ("was" because he died in 1982--more information here if you're interested).
I will probably be offline all weekend, until late Sunday or possibly Monday, though I might have a chance to look in once or twice.
