Luminiferous Extravaganza (sp?)

Unknown London Light Show that according to this advert were a Light Show from the Middle Earth Club in Covent Garden, London however they have not appeared on any Middle Earth adverts that I have seen to date.

Unfortunately I have no personnel information for Luminiferous Extravaganza so please contact if you can assist as always :-)

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