What Can't You Find On The Internet?

Andy Partridge once wrote a mini-essay (or post?) about songwriting in which he used an extended metaphor about going around a racetrack built by his forebears (the Beatles, the Move, the Kinks, etc.) This may have been a myspace post? Or maybe that's just where I originally saw it, in my memory. It's not in the Complicated Game book and I can't seem to find it on Chalkhills (it wasn't really "news" or "press").
