Tune:?

On top of my ice cream, all covered with sauce,
I lost my poor gumdrop when somebody coughed.
It rolled off the table and on to the floor,
And then my poor gumdrop rolled out of the door.
It rolled in the garden and under a bush,
And then my poor gumdrop was nothing but mush.
Oh, the mush was all sticky, as sticky as could be,
And early next summer, it grew into a tree.
Oh, the tree was all covered with beautiful moss,
It grew yummy gumdrops in butterscotch sauce.
So if you eat ice cream all covered with sauce,
Hold on to your gumdrop and don't ever cough!
