Deryck Whibley joined Good Charlotte on stage at Aftershock Festival for a surprise performance of two Sum 41 classics, ‘Fat Lip’ and ‘In Too Deep’.
Sum 41 gave their final live performance earlier this year at the Juno Awards in Vancouver, where they were inducted into the Canadian Music Hall Of Fame by Good Charlotte’s Joel and Benji Madden.
Good Charlotte’s latest album ‘Motel Du Cap’ was released this year, and they have been announced as headliners for Slam Dunk 2026 at Hatfield Park and Temple Newsam in Leeds.
The 20th anniversary edition of Slam Dunk will feature Good Charlotte as headliners, with more acts to be announced for the event.
