QI recently saw an episode of "The Adventures Of Rin Tin Tin" on Antenna TV. In one scene, new background music was added, which included a heavy metal sounding guitar, which did not exist in 1955, when this episode first aired. Although it was an action sequence, the music was mixed in so loud, that it was hard to hear what little dialogue there was. At the end, they froze the picture & new credits rolled passed the still shot. Does anybody know anything about this? Just curious.
