Lyrics:

When you sing* I want to sing
When you sing, I want to sing.
Makes me want to sing, Mother,
sing, sing, sing
When you sing I want to sing.

When you smile I want to smile
When you smile, I want to smile.
Makes me want to smile, Mother,
smile, smile, smile
When you smile I want to smile.

* Can be substituted for something else: laugh, etc.
