I've got the joy, joy, joy, joy
Down in my heart (Where?)
Down in my heart (Where?)
Down in my heart
I've got the joy, joy, joy, joy
Down in my heart (Where?)
Down in my heart to stay

And I'm so happy
So very happy
I've got the love of Jesus in my heart
And I'm so happy
So very happy
I've got the love of Jesus in my heart

I've got the peace that passes understanding down in the depths of my heart...

I've got the wonderful love of my blessed redeemer way down in the depths of my soul...

Well, if the devil doesn't like it he can sit on a tack...
