Wayne Newton on The Bachelorette. 

Wayne Newton brought some Vegas magic to ABC’s The Bachelorette on Monday night. 

The nine constants paid a visit to the veteran entertainer, known to his fans as Mr. Las Vegas, and his wife, for some advice on wooing the ladies with song. Newton, in mentor mode, challenged the men to write new lyrics for his signature song “Danke Schoen,” with a simple twist: they had to perform it for Bachelorette Becca Kufrin.

Wayne took the guys -- who he nicknamed the Bachelorette Rat Pack -- to the Aria Resort and Casino where they tried to weave their own musical spell. Check out the video below.
