Facts or Fiction?

I never cease to be amazed about Naperville's role in the world. Today I was told that it played a part in a classic Carpenter's song. You know, Sing, Sing a Song? Well apparently the famous "la, la, la, la, la," accompaniment was sung on the record by children from Beebe Middle School. So far I haven't been able to confirm this, so feel free to tell me if you have the definitive answer. Here are some other facts about Naperville that may not exactly be true, but if they're not, they should be.
