Madelyn's got J-O-Y

Turn up the volume. This might be hard to hear at first, and in case you have trouble understanding, here are the lyrics:

I've got joy down in my heart
Deep, deep down in my heart
Spell it
J-O-Y down in my heart
Deep, deep down in my heart
Who put it there?
Jesus put it there and nothing can destroy it, 'stroy it, 'stroy it!
Huh! (With a karate kick for emphasis)
