One idea, "borrowed" from this:



is an MJ / Ceroc around the world event.

This ought to be related to some significant event in the MJ timeline

or some other major event - e.g. the Olympics

I would prefer it to be an annual event.

It could be linked to a world record attempt - most dancers dancing to the same track at the same time. (Which track?, and why?)
