Too many things to try to quote them all ...
Vitriol towards I Can't Dance - Yep, I'm one of those who would rather that one be left in a waste bin. I didn't care for the video (which was always on MTV), I didn't care for it on the radio, I didn't care for it on the '92 tour, I didn't care for it on the '07 tour, and it is an always skip on the album or any live releases. I know lots of people really like it, so I am glad for them that they get to experience as often as they do. But I could go on living forever without hearing it. <shrug>
Duchess - Seeing and hearing clips of this on YouTube almost made me reconsider my decision not to go tonight or tomorrow (the Chicago shows, as I type this). That's such a great song anyway, and this version sounds amazing. I wrote this somewhere else, but that moody instrumental opening could just go on for much longer before the break into the song.
The Lamb - I agree with whomever previously said that the Lamb is great in any form. I have only experienced the acoustic version via YouTube, but I really liked it. It's very different, and I really like that they took a chance on it. Sure, they could have done an acoustic Hold on My Heart or something. But I like the left turn for this one.
Abacab - I wonder if that might have been an option vs Fading Lights? Both songs that lead to long instrumentals at the end. Maybe they were thinking Abacab could lead into Cinema Show, but they liked the quieter option instead? I don't know. Either way, I agree with many here who wish that they played at least a little of the FL instrumental, and had come up with a better transition.
Regardless - to all who are going to the Chicago shows tonight and tomorrow, make enough noise that I'll be able to hear you in Uptown!! Have a great time!
