Priscilla Presley is using her late husband Elvis Presley's secret pre-show routine to help her win reality T.V. show Dancing With The Stars. The king of rock taught his widow a mental regime, including a secret chant, that he used to ensure he was in the best shape to perform. And Priscilla is convinced it can help her to victory - after watching the bizarre effect it had on her late husband. She says, "It was like Elvis was charging his batteries using this 15-second technique, and by the time he reached the stage, he was actually glowing. I just picture Elvis looking at me, and it gives me a sense of energy I've never had."
