If you remember my daughter's version of 'Angel's We Have Heard on High' you'll be delighted to know she finally "learned" the other portion.
"Angel's we have heard and saw, angel's we have heard and saw, sleeping, sleeping all the time...ooooo..."
My husband and I laughed and he said, "Angel's just sleep all day on the clouds. They have nothing better to do." I think he said it was boring, but I can't remember for sure.
