Hat-tip to Gary Jenkins for the link to this video.
This is one of “1,000 random acts of culture” to be performed over the next 3 years in the US. in this one 650 choristers enter the store and sing the Hallelujah Chorus from Handel’s Messiah. You probably know that when it is played traditionally that everyone stands for this chorus. It goes back to when George II first heard it he stood up and as royal protocol dictates that if the monarch is standing so too does everyone else, everyone else rose. The tradition has lasted since then.
Fabulous idea. Enjoy!
