I used to love the PBS channel as a kid, back in the “Reading Rainbow” days. I still remember that cheezy ass theme song like it was yesterday. Nonetheless, the PBS channel kicks ass bringing in some real shit, non corporate brouhaha, especially good music stuff. Tonight! Be sure to check out the 40-year old Johnny Cash documentary: “Johnny Cash: The Man, His World, His Music.” Made made over several months in 1968 and 1969, the doc is a classic. Check it out.
