Fans were decidedly NOT taking it easy when a physical fight broke out in the crowd during an Eagles concert in London’s Hyde Park on Sunday. The Eagles were headlining London’s annual British Summertime Festival (aka BST Hyde Park, which also featured Elton John, the Rolling Stones, Pearl Jam, Little Big Town, Duran Duran, Grace Jones, and more) when multiple scuffles broke out, according to the Metro. The band kept right on playing — with Deacon Frey singing lead vocals — as security tried to manage the disruption.
