I awoke this morning to a quite surprising message out of the blue from one Mr Jamie Stewart
"Hi James. I wanted to send you some promo pics of Ritual, since there aren't any elsewhere. It would be great if you could stick them on the page Thanks! J"
Why yes, Mr Stewart, we'd be delighted to oblige!
No dates were provided with these, but common sense suggests they have to have been taken sometime between 1979 and certainly no later than '83.
