Dave Grohl has incurred the wrath of Swifties after insinuating that Taylor Swift's show isn't played live. The Foo Fighters frontman told a London audience that his band has dubbed their show the "Errors Tour" (Swift's tour is called the "Era's Tour") because "we actually play live." Grohl has previously praised Swift and some speculate that the Nirvana legend is taking aim at the singer after his 17-year-old daughter criticized Swift's private jet usage and was then harassed by Swifties. Here's more from Deadline.
