The two Milan gigs had near-identical sets. The full songs were the same, though a couple of snippets differed. So if you want to hear the full thing, it won't make too much difference which night you track down.
Y'know what will end up happening. All 9 of the songs will be downloaded from iTunes for a cost of $9.00 (US) and then the whole thing will come out and I'll end up buying them all over again. Damn!
