'U2 WAY' STREET

Looks like the street has a name now! After shoveling their way into David Letterman's studio the day before, U2 – (from left) Adam Clayton, Bono, The Edge and Larry Mullen, Jr. – take Manhattan, temporarily renaming a portion of W. 53rd Street U2 Way on Tuesday. The band released their twelfth studio album, No Line on the Horizon, on the same day.
