here is the version I learned and sang to my kids:they call it
"The Peep Song"

Go to sleep my Baby
Close Your dreamy Eyes
Angels up above you
Are watch-in on my honey
From the Skies.
Great Big Moon M Shining,
Stars Begin to Peep
Time for Little one's Like you dear
To go to sleep.
That's my one my only Lullaby

Some times sing it twice , but my kids would come to me and ask Daddy can you sing the pee song to me lol they called it that because of the one word peep in the song lol cute lil thing kids do it was a sweet favorite of them when they were little , hope that helps Neal
