Are there any historical recordings of fluent ex tempore Latin used in university lectures, such as for theology or philosophy courses, in academic events, or in scholastic disputations? I'm looking for audio between circa 1900 and 1960.
The closest I've been able to find to this is Wyoming Catholic College's Dr. Jeremy Holmes reading St. Thomas Aquinas's Compendium Theologiæ and explaining its grammar ex tempore in Latin (source: Latin resources here), but it is fairly recent (2010).
