U2

1. An American spy plane that flys at high altitudes to avoid detection and interception. (see U-2)

2. An Irish rock band featuring Bono? (Paul David Hewson) on vocals and guitar, [The Edge]? (David Howell Evans) on guitar, pianos, vocals, and sometimes bass, [Adam Clayton]? on bass and sometimes guitar, and [Larry Mullen]? on drums. Pretentious and utterly tedious, the band has re-recorded their first hit single "Gloria gloria over and over again" many thousands of times with different titles and a new chord here and there, thus acquiring an enormous and enormously dim fanbase. They are politically wanky in human rights causes.
