Rocker Bruce Springsteen will help to mark the 20th anniversary of Steven Spielberg's university foundation by performing at a special benefit gala. The Born in the U.S.A. hitmaker will be joined by host Conan O'Brien and special guest Liam Neeson at the Ambassadors for Humanity gala in Los Angeles on 7 May (14). The event will benefit the filmmaker's University of Southern California Shoah Foundation - The Institute for Visual History and Education, which was established in 1994 with the aim of overcoming prejudice, intolerance, and bigotry through education. Spielberg says, "I am personally honoured that Bruce, Conan and Liam are joining me and lending their considerable talents to this year's special 20th anniversary gala. Not only do they entertain and inform us through song, laughter and words, but by helping us commemorate this significant milestone, they also draw attention to the vital work of the USC Shoah Foundation." U.S. President Barack Obama will also be in attendance and will be presented with the Ambassador for Humanity Award by the Lincoln director himself.
