When I was a student at Ushaw College in Durham I recall seeing an old film of High Mass at the College from the 1960's. I've never been able to find it on the internet but my attention has been drawn to the fact that Fr Peter Kravos, a contemporary of mine at the seminary, has uploaded them to YouTube. Thank you Peter!
There is also this documentary.
And another High Mass!
What a fantastic sight and sound to see and hear so many in the glorious chapel and how sad that it is now closed as a seminary.
