What is the name of the music in the simpsons episode when bart and milhouse sees the answer book?

I was watching thw episode where bart and milhouse go to a library or bookstore, and then the lady shows them a book. and she gives a preview of whats it in and while tht happens, there is a song that plays, I REALLY WANT TO KNOW WHAT SONG IT IS. PLZ TELL ME it sounds like a whole group chorus singing, ull know it when you hear it.
