Myself, I thought this was how it was done:

Holding Hands

Elephants walking
Along the trails
Are holding hands
By holding tails.

Trunks and tails
Are handy things
When elephants walk
In circus rings.

Elephants work
And elephants play
And elephants walk
And feel so gay.

And when they walk
It never fails
They're holding hands
By holding tails.

By Lenore M Link

Of course, I would have to consult the elephants...
