I don't think Donny was condoning the lack of a real keyboardist just saying that technical stuff like that is handled by the sound guys. Some acts who rely on a lot of special pre-recorded effects have everything backed up for just this scenario.
It sucks but its happeneing more and more. Big fights with musician Unions over replacing live musicians in theatre productions.
Van Halen certainly should of hired a real keyboardist. He could of gotten any 14 year old kid he found in a Guitar Center playing Jump on the newest synth.
