Mother nature didn't agree with Guns 'N Roses' plans on Thursday night in Germany.
First, the band delayed the start of their concert 15 minutes to make sure everybody had time to enter the venue, the Messegelände.
Then, four songs in, a thunderstorm blew in during "Welcome to the Jungle" which forced GnR to leave the stage for 90 minutes.
But when they returned they rewarded fans with a surprise appearance by AC/DC's Angus Young who assisted on the classic "Whole Lotta Rosie."
Here's a couple different views.
