Mumford & Sons performs at BST Hyde Park in London on Saturday, with several prominent figures reported to be in attendance. Coverage notes that actress Carey Mulligan supports her husband, Marcus Mumford, during the group’s set. The reports also say Dianna Agron watches the performance. The articles frame the moment as part of a broader “ladies in their life” theme, linking the performers and attendees to individuals associated with band members. One account additionally references Winston Marshall’s former association in connection with Agron, though the core reporting remains centered on who is seen at the show and the appearance of Mulligan and Agron as spectators. Both sources describe the concert as taking place at BST Hyde Park and identify the same highlighted attendees. No additional details about the setlist, crowd size, or any events during the show are included in the provided text.
