Prior to Festelle there was a group in UK called Sportsfighters. It was run by a guy by the name of John Brotchie, who, as I understand it, had a martial arts background. John married a girl from New Zealand and moved there and started another Sportsfighters group there. I have no idea if either of the Phils were involved with the UK Sportsfighters in any way, but they may well have been and that could have been the precursor to Festelle.
Somewhere I have a report from a NZ magazine/newspaper on John Brotchie which I will see if I can dig out and post.
