Stower - I have been involved in 'Medieval Banquets' for a number of years - The LAST thing the average attendee wants is Authenticity , especailly with the music !
We did have a Re Enactment type turn up dressed like a very Low Class Farm worker and request some 14th century Madrigal . Every one else was in Silks and satins and Armour , so he just looked totally out of place .
