Lady Gaga's Mayhem Ball concert in Brisbane experienced significant delays with gates opening an hour late due to technical issues during sound check. Thousands of fans waited up to two and a half hours in 29-degree heat, resulting in one hospitalisation for possible heat exhaustion and another person fainting. Internet personality Johnson Wen, known as Pajama Man, was spotted by fans and security and escorted out before the concert began, with police issuing him a move-on notice.
