I have heard the dirge version of Go Tell It On The Mountain. Your choir director must have a friend in Maryland. It is indeed awful.
Re: the reading: once I accidentally gave a family member a book that she had already read (knew she liked the author, took a guess). We chatted a bit about how she enjoyed it, but no longer had her copy so I said "Oh, good, well I guess you can read it again now!" To which she replied: "Why would I do that?" She wasn't being snarky, and she didn't mean "This book isn't worth a second read" either. She meant, wholeheartedly, "Who would read a book they had already read ? Ever?"
I....um....okay. I just mentally moved her from the "Big Reader" to "Reads" category and went on my merry way.
