This one, from November 1968, was not conducted in person and contained no fireworks. But I so love Buckley’s line on big government:

There is no dropping out of our centralized society. The feds want you. They want your income and your vote, and they want to take your temperature and your pulse, and they need to know how many toilets you have in your house so that the Department of Health, Education and Welfare can recommend proper import quotas on Canadian pulp.

(If you’re willing to sit through Gore Vidal’s commentary, you’ll be rewarded with a 1968 Pepsi commercial at the end.)

In this one, from October 1968, Buckley speaks about what sort of man the president should be. Quite relevant today, given the prevalence of the Obama cult of personality:

He shouldn’t form too high an opinion of himself. For instance, he should recognize that America is a great deal that has nothing to do with the presidency — millions of men, women and children who deserve the opportunity to dream their dreams without any reference at all to the man who occupies the White House.
The best-run country in the world is Switzerland. And I have often amused myself while there by asking casually what is the name of the president of Switzerland. Inevitably, there is an embarrassed silence — no one can remember his name.
