Move When the Spirit Says Move....
I learned it many years ago (and subsequently taught it to many, many children through the years) as "Sing When the Spirit Says Sing."   The third line went "When the spirit says sing, ya gotta sing right along, " Then on additional verses, we'd substitue the word "sing" with whatever the kids could come up with. Laugh, cry, love, rock, shout (they loved that one), pray.

In my many years as a preschool teacher, music was a very important part of our daily routine, and the helper of the day got to choose the songs for that day. One little guy stumped me for a few minutes when he said he wanted to sing the song about the ghost. Took me a few minutes to figure out that he waas talking about that song. Between the word spirit and the minor key, he interpreted ghost.

Train is a Comin' was another very popular one with the littles.
