Guest, You probably should be clear with us (and your organizers) When this Arthur is supposed to be from.

Gildas (an Early Text source) places Arthur 5th Cent. CE

Welsh writings seem to indicate closer to 8th century.

The Court of high chivaly with, Galahad etc... is entirely a 12 century invention. (Centering in France).

Arguably the most famous book "La Mort Arthur" is from the late 15th century.

Much of what the public recognises as fashion comes from PreRaphaelite paintings of the late 19th century.

All of these have their own popular historical value.

Perhaps more useful to you would be some sort of profile of who your audience is and just what sort of message you are trying to convey?

If you are asked to represent them all I suggest you be broad in your music selection or seek to reflect the diversity with more than one show.
