I found out about this today on another forum. It looks like there's one bonus track. Looks like the UK track listing aswell with the bonus track being World In Harmony, which is tagged on at the end. I just hope the remastering and updated packaging is acceptable. I'm also hoping that this means that the rest of the catalogue is going to get the same treatment soon. Hopefully 1970's Kiln House to 1974's Heroes Are Hard To Find and 1980's Live to 1990's Behind The Mask will follow, although I'm not holding out too much hope yet. The new Deluxe Edition of Then Play On is being released by Rhino/Warner.
