It was 40 years ago today–Dave Devall was on the air at CFTO eight years already–that CBS fired the Smothers Brothers. David Bianculli, who is almost finished his book on the boys, has the heads up today over at TV Worth Watching. Celebrate by defying authority, protesting the war and calling the brother your mom always liked best. Better yet, run out and buy or rent The Best of Season Three Smothers Brothers Comedy Hour DVD boxed set. It’s a groovy blast back to the trippy ’60s, an era when dissent on prime time TV was almost as verboten as it is today.
