Dave Grohl poked fun at Taylor Swift’s “The Eras Tour” while onstage at London Stadium on Saturday, as their show happened to coincide with Swift’s nearby show at Wembley Stadium. Grohl quote: “So we like to call our tour the ‘Errors Tour.’ We’ve had more than a few eras, and more than a few (freaking) errors as well…That’s because we actually play live. What?! Just saying.”
