On the whole 'underrehearsed v experimenting' issue-was it the later 360 tour shows where EBW first made an appearance?I seem to remember various versions of this song basically being tested out onstage,as if the band were excited enough about the song to allow fans an insight into their creative processes.They played about with different arrangements,and weren't bothered by false starts on those occasions.
Almost midnight in NZ as I type, which means this time next week show #1 will have finished and we'll know a lot more than we do now in terms of stage, visuals and set list changes.
