The comments for Lee Hong Ki's performance in King Of Masked Singer are crazy:

I was watching TV while I was washing dishes and after a long time I heard Lee Hong Ki singing on TV, when I turned my head and looked at the screen, he was wearing a mask, this was ridiculous.

It would have been more surprising if he had just taken to the stage saying "voiced by Lee Hong Ki".
