I used google to check. Love the 1812 Overture when done with howitzers. After the Soviets fell it was performed in front of the capitol on the fourth of July, with the Air Force Glee Club singing the Russian Imperial Anthem at the end of the Overture. Great Stuff.
When my boys were in the military they had an orchestra play the 1812 at a local park and my boys fired the howitzers. Hubby got a night pic of the “flames” coming out of the howitzers. It was awesome!
