I'm going to tell you a story...
There is a small town in a large state and they have a community theatre that puts on plays and an annual musical.
After 25 years of volunteer musical directing, the musical director had a bad stroke. Although she did not die, she had trouble moving and could no longer conduct. The doctors said she would have to do rehab for a few years to get back to normal.
The next year, the theatre held an entire season of musicals in her honor. The musical director who replaced her was a student of hers.
They did her favorite musical for the close of the season, HELLO DOLLY. At the opening night performance, when they got to the "Hello, Dolly" number, instead of the Dolly Levi actress appearing at the top of the steps, it was the musical director. The entire theatre stood up instantly and cheered. There were screams and tears. The balcony, mezzanine, and orchestra stood up. Then the REAL orchestra (the musicians) stood up.
The Dolly Levi actress came out and joined the musical director. Together, they walked down the staircase as the show resumed. When the song finished, there was another ovation. The show finished.
She resumed the musical direction for the rest of the shows. She is still the musical director to this day.
"The Spectacle has, indeed, an emotional attraction of its own, but, of all the parts, it is the least artistic, and connected least with the art of poetry. For the power of Tragedy, we may be sure, is felt even apart from representation and actors. Besides, the production of spectacular effects depends more on the art of the stage machinist than on that of the poet."
