Playmate,Come out and play with me
And bring your dollies three
Climb up my apple tree
Yell down my rain barrell
Slide down my cellar door

And we'll be jolly friends
For ev-er more!

Fiberbabe! ... Oh, what memories you have conjured up! I remember the above (changes in blue & bold) as a song from my far distant youth! Late 1930, early '40s.
Perhaps it was adapted later to a clapping game ?!?!?!

Oh, yelling into a rain barrell produces a booming hollow voice. And exterior cellar entrances had doors you could slide down! Fun!
