What did the king do during the hallelujah chorus of the messiah?

During the Hallelujah Chorus of Handel's "Messiah," it is traditionally said that King George II of Britain stood up, prompting the audience to rise as well. This act of standing is often interpreted as a sign of respect and reverence for the music and the message of the piece. This tradition continues today, where audiences often stand during the performance of the Hallelujah Chorus.
