This story appears to be true, and it explains why we consider it a tradition to stand when the "Hallelujah Chorus" in Handel's Messiah begins. This is a famous song that is often played during the holidays. The Messiah premiered in London in 1743. The legend states that during this performance, the King was so moved by the music that he stood up. As people generally stood up whenever the king did as a matter of formality, this caught on, and it created a tradition that remains to our days.
