In the very likely event that Jeffrey Goldberg does not read my unsolicited email, I would like to go on the record as saying that the Christmas carol known as "I Heard the Bells on Christmas Day" was written by Henry Wadsworth Longfellow, and not, as Goldberg states, by Johnny Marks.
This carol is often said to be "based on" Longfellow's poem, but that's pretty weak. If I could get credit for "adapting" poems merely by deleting two stanzas and changing the title, I'd get a lot more author credits.
Update: Hey, how about that! Thanks for reading my email, Mr. Goldberg! Now I can sleep easy.
