Lyrics:

Fill my life with a song a happy happy song
And let the whole world sing it with me
As long as you're mine there's happiness in every line
And that's the way that our love will always be
When you smile you turn all the rain a sunshine
When you laugh it's like a pretty melody
So fill my life with a song a happy happy song
And let the whole world sing it with me
[ guitar - steel ]
Fill my life with a song a happy happy song...
Just let the whole world sing it with me
