The guy is using the keyboard as a "prop"... just like the light show, or even his hat..

I know players that use a keyboard as a buffer to the audience, or just as a player (media)..

I have seen big name country singers that strap on a guitar...and don't play it...lust an image (prop)..

I have seen decent singer/ piano performers rely on their back up keyboard players..

Or well known gal singers (stars) that can't sing without a pitch correction or studio backing track..

So to call this guy a fake, and not look at the entire entertainment business doesn't seem fair..
