Famous Entertainers of the 20th and 21st Century!

This list applies to talented people who are a triple threat by being able to sing, dance, and act. I wrote the term old-school vs new school entertainer to distinguish the difference between entertainers from the past and present. For example, I caused Sammy Davis Jr an old school entertainer because he had to sing, dance, act, and even do comedy at the same time during his shows, which was not an easy thing to do. A new school celebrity, e.g. Beyonce, is someone who made the transition from singing, dancing, and acting throughout their career. Makes sense? I know I might have messed some famous entertainers from the old school generation; if so, please let me know which entertainer you think deserves to be on the list. Thanks. (Please note: I am not going to include Lady Gaga on this list. While she can sing and dance, I have yet to see her star in a motion picture).
