Might be on National Review archives, if nothing else. So much is available online these days, when we used to have to look in the “Index to Periodical Literature” and find back copies in a college library!
I don’t know if you are aware of it, but there are hundreds of William F. Buckley “Firing Line” DVDs available on Amazon. During the long, long life of the TV program, he interviewed almost every major figure, politic, literary, and artistic.
The level of intellectual discussion is fascinating to watch in this day of the 30 second sound sound bite.
I also love watching the old Archbishop Fulton J Sheen program. I think they are on DVD as well.
The re-runs of Sheen’s various programs are aired on EWTN. Re-runs are also aired on TBN.
