LONDON (AP) - He's no gang banger, for sure. But Paul McCartney has been doing his share of drive-bys lately. In his case, the drive-bys are performances. He pulls up on a truck and performs off the back, surprising passersby during lunch hour. He did it in New York to help promote his album "New." And he did it again this past Friday in London, stopping at Covent Garden - usually home to jugglers, mimes and other street artists. Thousands of area workers and tourists got to take in the performance.
