The Latin Mass Society have sent me several very long documents, asking me to post them here. I think that actually you would prefer to read them on their own site, where you can also see photos.
Here is a link to their own press release about the Mass in Westminster Cathedral.
Here is a link to his Eminence's talk at the AGM meeting after the Mass.
And here is the Cardinal's homily at Mass.
And, for those who like this sort of thing (like me), here you can find lots of photos of the great occasion.
