Foo Fighters frontman Dave Grohl appeared to make a shady comment about Taylor Swift during a recent concert in Manchester, suggesting that she doesn't perform live like his band does. He referred to his tour as "Errors Tour" in contrast to Swift's "Eras Tour," insinuating that she doesn't play live. This led to backlash from Swift's fans, who criticized Grohl for undermining the talented pop star. However, some defended him, claiming it was just a joke. Grohl has expressed admiration for Swift in the past, even calling himself a Swiftie back in 2015. As the controversy swirls, it remains unclear whether there is any bad blood between Grohl and Swift. Ultimately, it appears to be a case of misinterpreted humor rather than a genuine feud between the two musicians.
