I’ve been a big fan of this tune for some time now. It’s off Van’s “His Band and the Street Choir” album from 1970 and you should probably grab it if you can.
But since I am a great guy , I found an excellent remix that Rayko did a while back, that takes the original material and makes it longer. That pretty much took care of my only complaint about the tune.
You can download a copy of his version HERE.
