They've obviously rehearsed Daybreak, it's immense. What a shame they never played it. It was a highlight on the 1995 tour, but with Reni it's a whole different level. Albeit through the mixing desk - not sure how well the intricacies would come across through a stadium PA. That's their fault though for only playing big venues.
I'm guessing there just wasn't room in an already-long set for it. I'm guessing they couldn't find space for another "jam". For the casual fan that went, given the choice between Daybreak and Fools Gold or Resurrection it's probably a no-brainer.
