Lullaby

For some strange reason, Katie Grace and Daniel are both digging this lullaby lately:
Arrorro, my baby,
Arrorro my own.
Arrorro my baby,
Sunshine of our home.
Sleep will not come to you,
Always runs away.
Lovely little baby
Wants the sleep to stay.

I've been looking all over the internet for a place that plays the tune, but no luck.
