When Barret Hansen, better known as Dr. Demento, recently ended his weekly show, he had spent 55 years spinning weird, silly, or otherwise strange songs on the radio or online. No mere fringe figure, he was an influential figure in American comedy and one of the most important cultural libertarians of his era.
That might seem far-fetched to people who grew up in a post-SNL, post-Seinfeld world. But in the early 1970s, all that lay in the future. Television shows still had to pass strict censorial review to be aired, and the same code policed much of what could be heard on mainstream radio. Hansen's program pushed against those strictures.
