Mary, it doesn't surprise me that you are the first to attempt this quiz. I said in the Secret Santa Goofy hints that I thought thinking was your forte.
Try again on 6, 13, 22, 24,31, 32, 33, 34,35,36,37.
Hints:
14 - both not either 31, 32, 33, 35 - earlier 37 wrote, and not sang
Ed, I do agree. I love a good info-detective session, but it is fun to give the questions a go initially, just to test the brain. The fun thing about this quiz is, we hear so many Christmas carols, endlessly, but when someone asks a specific question the answers seem to be buried deep in the subconscious and are often hard to extract.
