It looked like perhaps somebody had run on to the stage? Wagner was trembling at the start and kept looking camera right and mouthed something at somebody.
I assume there was a problem which delayed the start of Wagner's performance. For those who didn't see it after the his intro the camera cut to Dermot who was standing next to Louis, who asked Louis what he expected from the performance (essentially filling for about 20 seconds) before the start of the performance.
