A source said that the presenting rivals had practised their performance at studios in West London, telling the Mirror:
"It sounded great. There was a bit of a crowd gathering to listen when word got around they were in the studio.
"Nobody could work out why those three celebrities would be working together on something. It was a huge shock."
After their performance, Sir Bruce and Ant and Dec will go head-to-head for an award.
