CARTER-FINLEY STADIUM/ RALEIGH—As U2 ended its 18-song set Saturday night at Raleigh's Carter-Finley Stadium, Bono, the band's frontman, dedicated the night's singing to Ariel Dorfman, the Chilean-American novelist and poet who's taught at Duke University for more than two decades. In 1998, Bono, along with playwright Harold Pinter, contributed his voice to Deadline, a fictional film set to two of Dorfman's poems. The evening included a litany of such dedications, including one to the brother of guitarist The Edge and to members of the United States military in attendance. Still, for a band that hasn't played North Carolina in 26 years, the Dorfman nod was the most surprising of them all. A full review of the show will be posted soon.
