Yeah the subject has been indeed covered. You have to be sure to check your control panel (CP) and set your options in order to show ALL the threads (not just the most recent ones).

And yes, there are live recordings of the AF concerts, try WinMx or KazaaLite or other filesharing programs and you'll easily find them.
