I can't imagine they would ever play all of TBA. I imagine that even most fans who got into the band because of the big hits from that album would rather hear a more well-rounded set list, or all of MoP, than all of TBA. Besides, I thought James Hetfield dislikes "Don't Tread on Me" a lot, which makes that one of those songs I can't imagine them ever playing (which sucks, since that song is aces). And who in the world really wants to hear tripe like "Through the Never" or "Holier Than Thou"?
