Sweetness In Light (Hawaii)

Light Shows from Hawaii seem to be scarce, can only think of three (possibly four) but the poster below is for TWO - Sweetness In Light and Pan, neither of which I have seen reference to anywhere else but I'm sure they did more than this one show.

Can you help out with finding out who ran Sweetness In Light please as we have no active leads?

If you can help with more information about this Light Show we would love to hear from you.
