Watching a video of Yes' set from the cruise, at Wakeman (I think?) has (and this is what I count), at least 10 keyboards, some other midi controller, pedals, 3 laptops, and an FX rack.
Someone's got to let that guy know... all that technology and he's probably just scratching the surface of all of it, not realizing the days of needed a different piece of gear for each sound are over. I mean... Neal Morse was on the boat too, right?
