Welcome to the fray!

Why do you sometimes see one or more of the Drummers wearing a leopard skin?
This is an old British Army tradition. Strictly speaking, the privilege of wearing the leopard skin was granted to specific Army regiments as a regimental honour for meritorious service, usually in Africa. Because of this background, the use of the leopard skin in civilian bands is in somewhat dubious taste. (Note that modern bands usually do not use real leopard skins but imitations, because of the endangered species acts).
