An inventive director.

Once, at a contest of military orchestras, by the way, in Riga, our orchestra had to go through a ceremonial march past the competition commission on the plateau.
In front, the conductor conducts with a tamper-major. The orchestra behind him. The first line of tubes, trombones. The second series of copper breathing tools and other dudes. They go, they play, they try. The feet are in the asphalt. The submarines fly in different directions. clearly. It is beautiful. The Eger march is sounding!

And suddenly! Stones on the asphalt plate, at the tribune itself. Right flank, tuber, height of 190 cm, from all the scale impresses the booth on this stone. He twists his leg and falls on his stomach, raising his hands with the tube up. The musician’s instinct. A tool is more expensive than life.
The orchestra, continuing to go, on its right side, stumbling at the falling trumpet.
The musicians fall like the bones of a domino and the plates turn into a bunch of small.

The remaining part of the musicians, with stone faces, continues, as in nothing, to repel the step and roar in the tubes. The composition is no longer that. Only two votes remained.
The conductor, not seeing what was being done behind his back, finally heard the strange sound of the "Eger March", made a statutory turn and went back to the orchestra. He stopped him in front of the tribune, stopped the music and, appealing to the commission standing on the tribune, shouted:

"We showed you how the orchestras will run on the uncharted territory of the square! Now we’ll remove those stones and show you how the orchestra will go when it’s clean!” With these words, he raised the stones and demonstrably threw them off the side.
Return the orchestra to the original.
Again with the “Eger’s March” the orchestra went great!
