I got this from a reader. It is worth some attention:
Here is a link to a real nice web page for the 1962 Mass at the Cathedral of St Joseph in Sioux Falls, SD. Bishop Paul Swain.
Although quite nice looking and informative, they do not have links to all the pages, so you have to surf to find what you’re seeking.
There is historical and descriptive information under the heading "The Mass."
Schedules and wonderful photos of an actual Mass at the Cathedral under the heading "Our Community."
Bishop Swain’s implementation document under "Documents."
The "Resources" heading and some other links are not completed yet.
It appears to have started in October. There is a document by Bishop Paul Swain "implementing" the Summorum Pontificum, dated September 10, 2007.
The Mass is celebrated every Sunday at 1:30 p.m., on Holy Days, some Feast Days (like All Souls’ Day), First Fridays (low Mass), Forty Hours celebrations, etc.
