He was born Barret Hansen, being the proud owner of a master's degree in music from UCLA under that moniker, but he's far better known to millions of radio listeners as "Doctor Demento." In 1995, he celebrated his 25th anniversary of broadcasting the greatest novelty records of all time, both new and old. In that time, he's elevated the novelty record -- in all its myriad styles -- to a high trash culture art form. He's made hits out of 40-year-old records that no one had ever played, and was singularly responsible for the success of "Weird Al" Yankovic, whose song parodies debuted on his show. Hansen's journey from record collector to national personality is the journey of the radio everyman, but one also grounded in a solid knowledge of American music in all its glorious forms.
