Guns N' Roses set tonight at the Messegelände in Hannover, Germany, bore the marks of earlier days in that the show started late. However, this time it couldn't be blamed on the band.

The concert's start time was pushed back 15 minutes to make sure that everybody had entered the Messegelände. But four songs in, they were hit with another delay. A thunderstorm swept through the area during "Welcome to the Jungle" and the band left the stage for 90 minutes.

However, once they returned to the stage, the fans got a bonus treat in the form of a guest appearance by Angus Young, who also sat in with them when they played Australia in February. Axl Rose got to reprise the role he played last year of fronting AC/DC by singing "Whole Lotta Rosie" and "Riff Raff." The band posted a clip of the former performance to their Facebook page following the concert.

During their date in Zurich, Switzerland, a couple of weeks ago, Rose introduced "Whole Lotta Rosie" by disclosing a personal reason for choosing to cover it. "When I’m singing this song, I actually, in my head, I see this little dog of ours with me onstage, ’cause she’s always so f---ing happy,” he said. “Before we came to the show today, she passed away. So we’ll dedicate this to her. Kind of the whole show for me in mind has been for Rosie.”

Guns N' Roses will remain in Europe through July 15, but rather than take a break, they'll embark on a series of dates across North America that will run through Nov. 25. Although the tour will start proper on July 27 in St. Louis, they're going to play a special invitation-only show at New York's legendary Apollo Theater on July 20 that will be broadcast on SiriusXM satellite radio.
