Warped Tour founder Kevin Lyman recently did an interview with The Gunz Show where he discussed the logistics of Blink-182 playing the festival.
Everyone always says, ‘Bring Blink!’ And just as a sheer economics project, think about what Blink would cost and what you’d pay for a Blink ticket compared to a Warped Tour ticket. It doesn’t work economically for Blink. They’re always welcome to come back. The door is never shut for anyone, but they’ve just gotta figure out how to come be part of it and still make it work for that $40 ticket at the door.
