Just confirming that the three New Zealand Yesshows in 1973 never happened - for reasons that have never be clarified. Perhaps the cost of bringing all their equipment, etc. down here outweighed the prospective ticket sales?
Steve Howe would have been keen, since his brother lived in Auckland at the time. Rick Wakeman brought his grand 'Journey To The Centre of The Earth' set to the Western Springs outdoor venue in 1975 and played to a sizeable crowd. There are still a lot of Yes fans downunda!
