Comments: Bono and Edge appear via video to sing Happy Birthday at the 100th anniversary celebrations of the Harvard School of Public Health. A report by the HSPH says that they "sang a happy birthday song specially written for HSPH". However, as we have no more details about the song, we have listed this performance under Happy Birthday. We do not whether Bono and Edge appeared live via satellite or if it was pre-recorded, nor do we know where it was filmed - it was likely Dublin, but we have given the venue as the location where the video was broadcast as part of the HSPH's celebrations.
