Yes, this is one of many I learned at GS Camp May Flather in the Virginia mountains in the 1960's. I sing the words as above with a few small changes. "Dawn" instead of "Moon", plural "pinions", "I would never fly away" instead of "I would never steal away", and the "tekkera kwow kwow kwow" (no idea how to spell it) chorus. I understood it to be a Mexican lullabye.
