Even though the first day of the emo-nostalgia fest When We Were Young was canceled due to high winds in Las Vegas, Sunday’s set went ahead with Paramore’s Hayley Williams giving a speech about the history of emo and Avril Lavigne joining All Time Low to cover Blink-182’s “All The Small Things.” This comes shortly after Blink-182 formally welcomed Tom DeLonge back in the band, released a new song “Edging,” and announced that they — along with Green Day — would headline next year’s When We Were Young festival.
