U2 gives free concert at Brandenburg Gate

Irish rock band U2 returned to Berlin for a free mini-concert Thursday in front of the Brandenburg Gate, playing its classic singles and a duet with Jay-Z even as the show was obscured from public view by a nearly 6 1/2-foot high metal barrier.

Bono greeted the crowd with the German words "Berlin, Du bist wunderbar!" (Berlin, you are wonderful!) and the band played a 30-minute, six-song set that featured "Sunday, Bloody Sunday," "One Love" and "Beautiful Day."

Rapper Jay-Z appeared as a surprise guest and performed Bob Marley's "Get Up, Stand Up" with Bono.

The show, which was free to 10,000 ticket holders who snapped up the tickets online last week in just three hours, drew some controversy because of the barrier surrounding the gig.
