Here's an excerpt from the performance of the 1812 Overture played by the Boston Pops on July 4, 2016 accompanied by the 101st Field Artillery. The fellow in the white jacket is the conductor for the artillery. And he's reading the actual score that Tchaikovsky wrote that included the timing for the cannons. https://youtu.be/DtXUj-09PME?t=353 And here's another view of it, with fireworks and field artillery on display. https://youtu.be/zlbCakDfXfE Happy Fourth everyone!
