I have found this browsing on youtube: http://es.youtube.com/watch?v=7SqznUdyeIw&feature=related It is a great version of Natural Mystic with alternate horn section, does someone in here know where this come from? is it some kind of demo/rehearsal? or an alternate mix? where can I find it, other than there?
