This is the product of negotiation between the Artist's people and the venues. The shows would not be booked unless the parties agreed that the venue's technical specs are sufficient. The venue can meet the specs in two ways -- (1) by having the required equipment or (2) disclosing any deficiencies and having the Artist's reps agree to the show despite them. My guess is that with minor exceptions, all of the venues booked can accomodate most Roger's gear
I believe that the Aussies have run into this problem in their N. American tours -- certain venues have been too small to accomodate the Aussie's stage and lighting rig in its entirety. They just set up what they can and run with it.
