I got Six correct of a possible eleven which I had heard of. Eg, I might have guessed singing nun If I had been thinking more clearly.

I found the quiz very Britian-centric (to coin a compound word) Here in North America, "Christmas Number One" is not a common concept. In fact, this October when I visited England was the first I had heard of it.

Here are some Quiz Questions with a more North American Flavor.

Who were first a hit with the folowing

Snoopy's Christmas
