This should be viral, but isn’t (yet). I think that’s because each of the 600 people told their nine people, but the nine didn’t pass it on.
From the video’s description:
“600 words, 600 friends and 1 music video for “Nine People’s Favorite Thing” from the original Broadway musical [title of show].”
[title of show] is on my short list to produce someday. I’ll get there, I hope.
