I remember the song, we had the album and used to listen to it in the early sixties. First it was a beautiful song, and I mean beautiful. So stop picking on it. The words were like that in lots of songs back then for children, as were stories as they helped children become accustomed with the hardships of life. Lots of children's stories took on such themes as well. It was a different time I suppose but don't knock it till you've tried it at least. We liked it.
But as I recall the song (and I haven't heard it in 50 years or so), the words were more like "hush cried the goose, my little papoose, the bright apple falls to the ground. Over trembling leaves, or the voices of thieves, but you must sleep somehow somehow. Yes you must sleep somehow".
That's how I remember the words, but that's just from memory.
