You see folks, this is the danger of being too reactionary about news items. On the wise research of L in C / Gervase Webb and the expert evidence of Borchester Echo, it would appear that blackface morris is;

1. Not an essential tradition in and of itself. Other colours and masks will do, and were used.

2. Certainly has some unpleasant and racist connotations even though modern-day morris folk do not intend it to be so.

On the evidence and understanding of our own community, it is easy to see the school's decision as justified, even if I still do not completely agree with it.
