What's on TV? Thursday, August 21, 1969

In Saturday's write-up, I spent some time on the late-night talk show wars, now fully joined with the addition of Merv Griffin to the continuing battle between Johnny Carson and Joey Bishop. We've got a second sighting of Merv tonight, with an appearance on WCCO at 7:00 p.m.; since Arthur Treacher, Merv's sidekick, is on the show, it looks like an episode of his old syndicated show. Doesn't hurt the hype, though. Speaking of which, you notice that WCCO is showing Wednesday's show on Thursday; good old Channel 4, tape-delaying it a night because the news runs until 10:45 p.m. And while Dick Cavett isn't on tonight, Hugh Hefner is—and Steve Allen's on in the morning. What a deal!
