When you can't hear, you can't hear, Osmond said. I don’t care what you think. People think you can hear. You don’t know what to sing to. You don't know what pitch to sing in, and they go, ‘You know, it was lip-synched.’ just so you know, most of those big shows are [lip-synched] because they don’t want a mishap, and they want to make sure that everything is right.
