I did a Hotbot search of the Web and found thirty pages that had the phrase "galloping, galloping, galloping." I checked the pages that seemed likely, but none had the poem. I wouldn't have thought "galloping, galloping, galloping" would be such a common phrase, but there was headless horseman stuff in there, and a poem by Erica Jong, and a rhyme for bouncing babies on your knee (complete with a caution that you shouldn't bounce baby too roughly).
