I once played a show where my local band was the opening act for a bill with Ronnie Milsap as the headliner. A musician's musician, they guy can play anything, and did a sell-out local show every Wednesday night at a local jazz/wine bar: Sold out, every good musician in town was there to listen as he played WAY more than his country hits.
Turns out he has perfect pitch. He was touring with one of those midi grands, and the local tuner had it nailed, except . . . . it was moved to the edge of stage left until his turn came up. His crew rounded us and a few more people up (imagine men shoulder-to-shoulder all the way around a grand piano), and they would NOT let us roll it on one of those big-wheeled dollies it was sitting in: We all picked it up and crept it to the tape marks center-stage so as not to mess with the tuning.
Out of a company with so many great musical products, Yamaha takes the image and performance of the CFX's VERY seriously, I'm not at all surprised by their moving and maintaining it, probably with a crew dispatched from Japan just for that.
