On Thursday (September 4), 5 Seconds Of Summer popped by BBC Radio 1's "Live Lounge," and they brought along more than just their usual herd of screaming fans camped outside the studio. Watch 5SOS cover blink-182's haunting 2004 ballad, "I Miss You," and then stare speechlessly off into space as you realize that "The Nightmare Before Christmas," which is referenced in the song, is actually older than any of the four guys in the band. #mindblown

But, that's not the only 5SOS news coming out of the U.K. radio station today. "Radio 1 Breakfast Show" host Nick Grimshaw announced that Calum, Luke, Ashton and Michael will perform at BBC Radio 1's Teen Awards 2014, which Grimmy will co-host with Rita Ora on October 19 at London's Wembley Arena. The lineup also includes Ariana Grande, Rixton, The Vamps, Labrinth and Ella Henderson, so you should probably just start screaming now.
