The Foo Fighters hit Auckland's Mt Smart Stadium on Saturday night, delighting thousands of fans as they rocked well into the night.
But they weren't the only source of entertainment, with a sign listing prohibited items at the show, giving plenty of fans a good chuckle.
The sign, reportedly posted outside Mt Smart Stadium, began with a fairly standard list of banned items, including large bags, chilly bins, and commercially prepared food.
But look a little closer and you'll soon spot some more bizarre items - including "unflattering photos of Ryan Seacrest" and "derogatory press clippings of Shania Twain".
Other items forbidden from the show supposedly include leg warmers, "any pencil that isn't a number two pencil" and "Cream magazines that do no mention Ted Nugent".
