After finishing his six week limited run at the Las Vegas Hilton, Wayne Newton Mr Las Vegas had disappeared from Las Vegas all together. There was some speculation that his long run in Las Vegas was over. Now there is rumors that he will be taking over for Gladys Knight when she ends her long run at the Flamingo. I hope this is true because while Wayne Newton may have not had the best talent he was the ultimate showman and also put on a good show.
