Sandra, I didn't make it to Mayday this year either :-(

I think your Black Joak link might be old. Here's one that works - Black Joak Morris

And here's a link to the Australian Morris Ring which might help. I've noticed that the Sydney Morris Men's site is not up, but you are redirected to an article about the Wheeze and Suck Band, some of whom are in the Sydney Morris Men. John Milce or Ian Macintosh would be the ones to contact.
