Oh Mother, How Pretty

Some errors in your transcription. I have the album, with notes and lyrics.

The song is traditional; adapted by Joan MacIsaac.
Introduction:
"My mother sang this lullaby to me when I was a child and my grandmother sang it to my mother in the cradle. It's been passed down through the family for generations and, according to family tradition, originated in Ireland."

This song appears in A Poetry Book for Children, 1854, Appleton Century. Author unknown.
Jim Dixon posted the old lyrics in 2008.
How Pretty

If you were up there with me and my friends
We'd rock in an icy blue sea.
We'd sit in the middle and hold by both ends
As nice as a cradle could be.

There we would sit in a beautiful sky
Through fluffy white clouds we would roam.
We'd see the sun rise and see the sun set
And on the next moonbeam come home.
