Apparently there was a Solemn TLM yesterday in Harrisburg, PA at St. Lawrence Chapel.

Though this is an apostolate of the Fraternity, it was the first Solemn High Mass celebrated there since the post-conciliar reforms. For many of us it was also a first, as all but the priest who sung the Mass were seminarians from Mount St. Mary’s seminary. The seminary’s Schola sang and a number of us who have been practicing for some time served as Deacon, sub-deacon, MC, acolytes and thurifer. The reason was no more than the availability of a priest looking to help seminarians learn while improving the liturgical life of his community, and the allowance of the Rector to make the Solemn High Mass happen. [Excellent man. I met him. He was a real gentleman. If sounds as if he is trying to do his part as a rector to see to it that seminarians know both uses of their Roman Rite.]
Here is a YouTube of the event. There are others.
