Q. Why didn't the band have Xylobands at the Paralympics Closing Ceremony?

The Oracle replies:

The Olympic Stadium was fitted with individual LED lighting panels at every seat.
It wouldn't have worked if both the panels and Xylobands were used in full force so it was decided not to use Xylobands, though the athletes were wearing them.
