That's not from the 'Live at the Acropolis' Album. That song is called Marching Season, and its from "In celebration of Life' CD which I have. There are a few versions, I belive, of that song. Its also in one of his earlier albums called 'Chamelion days'. I have actually seen him perform this song live a couple of times, and it's pretty good. The drummer and him get going quite fast.
