The Killing Hand - would nice to see it performed with the studio intro instead of Another Hand. Would be even cooler to see the WDADRU arrangement.
Another Won - Absolutely amazing song, it's a wonder it wasn't included on WDADU. Personally I think it should have replaced LFAGA.
Space-Dye Vest - Of course. It would be amazing live.
Cover My Eyes - Very underrated song from the FII demos, it would serve easily as the first "rocker" of a setlist.
Hell's Kitchen/Lines in the Sand - We usually tend to only get the latter, and when they did play HK, it wasn't with LITS. So I think they should be brought back together.
The Great Debate - The keyboard intro gave me chills when I listened to a live version of it. Really needs to return and not get kicked out like last time.
Octavarium - Would be a really great live experience. Could work as an encore well, although maybe not since I'm not sure if it holds enough fan favourite status.
Repentance - Extremely underrated, would work for a breather from heavier songs.
Wither (Piano version) - This would work well before a song like Disappear or Space-Dye Vest.
The Count of Tuscany - Since this song does hold a significant place as a fan favourite, it could also work as an encore, but it works better as a set closer.
Breaking All Illusions - It was played the hell out of on the last tour, but it's so amazing. The kind of abrupt beginning with no build-up to the keyboard/guitar melody makes it perfect for an encore.
