I managed to get hold of the remastered version of Brian Jones presents The Pipes of Pan at Jajouka last week, the one with the changed cover. I think it's out of print but cdconnection still had it.
For me the outstanding track on it is the 11&1/2minute Your Eyes are Like A Cup Of Tea which starts with really reedy sounding pipes over a repetitive/hypnotic beat and keeps a possesed seeming drone going throughout. It is actually pretty psychedelic considering its acoustic non-rock source.
