Where did the tradition of audience clapping come from in Radsky's March?

When this piece was first played for Austrian officials, when they heard the bright rhythm of the music, they could not help clapping their hands and stamping their feet in the chorus. Therefore, this tradition has continued. Later, I knew that the audience of this tradition would applaud in the performance of Radsky's March, so this tradition began in Austria in 1848.

And we can also see the videos of 1974, 198 1, 1984, 1986, which have already been applauded by the conductor.

Therefore, the best answer is a false, nonsense, parrot-learned, unconfirmed rumor.
