I'll say.

If you can get your hands on the Genting VCD's or even videos from taiwan, malaysia or singapore to see all the different varieties of traditional and non-traditional lion dance you will be surprised to see all the varieties and to boot you get to see some realy good skills and acts from these competition teams.

A lot of the "new" lion dance routines involve poles and moving along very high poles.
This was developed from traditional routines where they would use a pole to lift the head and the dancer in the head up along side a building to get the greens.

Many times, the player from the tale would not go up with the head, but instead would steady the post with other team members while the head went up to get the greens.

In the modern dances, both members in the lion make their way along a series of poles and sometimes on double cable wires to get to the end of the series where the chang is. Then they return back along the poles and wires to dismount.

I had not heard of the "crab within a crab" version before, that is interesting.
the point about the sounds of the words business and crab rhyming is worthy of note also!
