Blink-182's Riot Fest show turned into an unexpected reunion. The band surprised the crowd by welcoming two musicians, their past member Matt Skiba and Descendents' guitarist Stephen Egerton. When Egerton took the stage, the band launched into "Hope," a Descendents track they started playing again last month. They included crowd favorites like "The Rock Show", "First Date", and "All the Small Things", which turned into a massive sing-along. Fans were happy to hear songs like "Keep 'Em Coming," "Sleepyhead," and "5-3-10-4," which hadn't been played live since 2015.
