Which Bishops celebrate the Extraordinary Form?

An extraordinary "thank you" to The Eponymous Flower for a very interesting piece of research that identifies those Bishops in the world who have celebrated Mass in the Extraordinary Form since Summorum Pontificum.
H/T also to Kate Edwards at Australia Incognita.

It is an impressive list and I was surprised to see that Great Britain had such a large entry. Well, we beat Croatia and Paraguay anyway!

Sadly, our Bishops tend to reserve this great honour for that once a year occasion at a Mass organised by the LMS (nothing wrong in that, just that it would be a good thing if it was once a month rather than once a year).

Also, many of those who do, fall into the Auxiliary category but I suppose we can draw some crumb of comfort from that as, presumably these are the mainstream Bishops and Archbishops of the future.

And now a little picture quiz - I hope that you enjoy it, sadly, no prizes for getting it right - you will see why.......
