Useless data interesting to nobody be me, but I figured out all of the songs I've seen them play live. Didn't know they were so consistent with the classics. Had no idea they played Sanitarium and FWtBT at 8 shows I've been too. At the same time I've only seen Horsemen once, and that was pretty recent, in a relative sense. Songs I'd love to see but haven't would be Blitzkrieg, The Wait, Orion, Bleeding Me, Outlaw, and Fixxer.
Also plan to see them twice at the Foro Sol in Mexico City in a few months. Hopefully playing three nights they'll dig up some relics.
