Tales from the Tour Bus has been one of this season’s most delightfully unexpected treats. Mike Judge has served up an animated history of country music, but based on newly collected oral histories that are themselves, at times, animated by him as well. And tonight’ Cinemax presents a mini-marathon of all three installments presented to date, so viewers can catch up instantly. And should. Tonight’s subjects, in order: Johnny Paycheck, Jerry Lee Lewis, and part one of the George Jones and Tammy Wynette story, which concludes Friday.
