That length of video can be uploaded to Google Videos but not to Youtube. I plan in future to use Google, partly for this reason but mainly because of Youtube's refusal to remove videos of various desecrations of hosts stolen from Catholic churches. I hope other Catholic bloggers will do the same.
Here are a couple more photos.
Notice the three Knights of Malta in choir dress in the picture below; the Order of Malta was (briefly) restored in England under Queen Mary and Cardinal Pole. The one nearest the altar is Mr Julian Chadwick, Chairman of the Latin Mass Society. Fr Osman is himself a chaplain of the Order (as well as the parish priest of St Birinus, Dorchester-on-Thames).
The Mass was very successful; the setting of Magdalen College Chapel is wonderful, and the Schola Beati Thomae Abelis sang extremely well under the direction of Mr Adrian Taylor. It was Fr John Osman's first Traditional Sung Mass. There has been quite a bit of publicity about these Masses, including an article in The Times; it even got a mention in the previous week's Tablet.
