What did George Mackenzie dance for?

It's very likely that you're thinking of George Balanchine, the renowned choreographer and founder of the New York City Ballet. He is widely considered one of the most influential figures in 20th-century ballet.

However, there is no record of a choreographer named "George Mackenzie."

To help clarify, could you please tell me more about who you are referring to? Perhaps you can tell me:

* Where did you hear this name?

* What kind of dancing are you interested in?

* Do you have any other information about this person?

With more information, I can help you find the dancer you're looking for.
