Last week U2 began their 10-date tour of New Zealand and Australia by having opening act Jay-Z come out to join them for "Sunday Bloody Sunday" and their 1981 super rarity "Scarlet" at Auckland's Mt. Smart Stadium. "Scarlet" (shown below) was played to celebrate the release of Burmese political prisoner Aung San Suu Kyi, and was mashed up with Jay-Z's "History," which he wrote after President Obama was elected.
The collaborations seemingly went off without a hitch, but the next night Jay-Z didn't come out during either of the songs. The tour continues December 1 at Melbourne Australia's Etihad Stadium.
