Serious fans of rock and roll will probably know the answer to this trivia question: When they were just starting out, the Irish band now known as U2 went by what one-word name?
The answer, of course, is "Radio X U2 History", a reference to one of the few technical terms that the fledgling rockers knew back then. The name didn’t last long, but the band certainly did—and within a few short years millions of fans were enjoying the sound of “Feedback” under their new name.
