It'll be hard work for them this time around - old songs to remember, new ones to learn. Probably they'll only play the songs that are in the same key, so they can play the same solo all over. Would be cool, cause we would hear a lot of songs from Some Girls and Blues songs in the key of A.
Probably they'll buy a new Casio keyboard for Chuck, hire Matt Clifford as second pianist and transfer the ancient art of weaving to the pianos! Damn, that'd be great :-)
Honestly, when they play like on the Licks tour and Ronnie's in a better shape I'm satisfied. Probably you say my expectations are low - but I got a fan during the Voodoo Lounge tour.
