Famous quotes containing the word radio:
“England has the most sordid literary scene I’ve ever seen. They all meet in the same pub. This guy’s writing a foreword for this person. They all have to give radio programs, they have to do all this just in order to scrape by. They’re all scratching each other’s backs.”
—William Burroughs (b. 1914)
