I will think twice about dipping my toe into scholarship again!! Thanks to those scholars who alerted me. My Ms. editor just added this note for me:
Author’s note: Since posting this article, scholars have reminded me that Shakespeare was not the inventor of the Shakespearean sonnet. Still, Mary Sidney did invent 126 different verse forms, and “Shakespeare” and Mary Sidney’s brother did make the Shakespearean sonnet famous.
Anyhow, yes, Mark M. the crow calls were pure magic.
If I make another video, I'll let you know, Mark S.
Thanks for your warm words, Annie and Martin and all.
