Query: This book is misleading...

I have read this book, done some research, and have found that there is no basis for this meaning of the song. It supposedly was sung by Catholics at the time to celebrate their faith in disguse, but nothing related in the book could reveal the person to be Catholic, even if you knew the "hidden meaning". Also, it was never specifically illegal to be Catholic in England, although for a time it was unwise. Just wanted to set the record straight.
