Philosopher's Stone

So I'm listening to a mix of Van Morrison stuff and his song Madame Joy is one of the most soulful songs I've ever heard. It's weird because most people have never heard of it, it wasn't even released on a studio album, just an album of songs that never made it. The album is called The Philosopher's Stone. And it's my second most favorite Van album (I have 15 of his) next to Astral Weeks.
