Seven Steps sounds very much like 'Zeven Stappen'. It's a Dutch children's song, and my Dad grew up with it. We live in the midwestern US.
You stand in a large circle, and hold hands, side stepping while you sign, and pausing to say the numbers, and do their corresponding action.

CHORUS:
Have you ever heard of the dansen zeven?
Have you ever heard of the seven steps?
Do you really think that I can't dance them,
I dance them like an edelman,


Een! (Stomp right klompen/foot, hands on hips)
Lock hands again: CHORUS
Een! (Action) Twee! (Stomp left klompen/foot)
Lock hands again: CHORUS
Een! (Action) Twee! (Action) Drie! (Down on right knee)

Keep adding each additional number and it's action as you go!

Vier (Down on left knee)
Vijf (Down on right elbow)
Zas (Down on left elbow)
Zeven!!! (Lie flat on the ground!)

I am very curious as to the origins of this song!! It's tradition for us!
