It’s been 50 years since The Smothers Brothers Comedy Hour premiered on CBS. Tonight, on getTV, two of the best 1967 episodes are repeated back-to-back. The first is a Season 2 episode guest-starring Bette Davis, who is the scene-stealing subject of tonight’s new Feud: Bette and Joan miniseries on FX. It also guest stars The Who, a group making its American TV debut (pictured is Tom Smothers with lead singer Roger Daltrey), and making it with a bang – an infamously out-of-control explosion at the end of “My Generation.” And then, at 2 a.m. ET, getTV presents the classic Season 1 episode featuring guest stars Janet Leigh and Simon & Garfunkel, who team up for a mind-blowing, taboo-questioning sketch called “Billy the Kid’s Birthday.”  Half a century later, both shows are astoundingly daring – and fresh.
