The best musical ever would have to be Les Miserables. I performed it in 2017 at Skyridge High School. I was in 4th grade, and was 9 years old. It was so fun, because my sister was Cosette! She was the lead! Les Miserables has been my favorite musical ever since then. Sadly, when we did it, I wasn’t used to those huge bright lights on stage, and I got sick for half of the time, so I only performed 4 out of 7 times. 
I love Les Miserables! It is also one of my musicals.
