Tales from the Tour Bus, by Mike Judge, is one of the sneakiest, most entertaining and original surprises of the current TV season. What he’s done here, basically, is a series of documentaries about country music and some of the stars’ reputed misadventures. And he’s done it with first-rate interviews, which are then animated and folded into the animated “action.” Tonight is part one of a two-part study about one-time country royal couple, George Jones and Tammy Wynette. She sang “Stand By Your Man” – then, for good reason, didn’t.
