"It's a pain in the butt," Farrell said of Lolla lineup leaks. "It's like you want to ask someone to marry you, and your friend jumps in and says, 'Hey, he's going to ask you to marry him.' You don't want to hear it from that person," adding, "It's been a thorn in our side."

Farrell was far more effusive when talking about this year's headliners, including New Order and the Cure. "Yeah, everyone is super excited for The Cure; they are like a fine wine, their songs have grown graceful and better with age," he said. "If you would have told me in the early '90s that New Order and The Cure would both be playing, I would freak out."

The Jane's Addiction frontman was equally excited about Mumford & Sons, who exceeded expectations with their latest album, Babel, both in terms of sales and walking away with this year's Grammy for Album of the Year.
