Dennis Sheehan, U2’s longtime tour manager, has died at a Southern California hotel, a day after the band kicked off a five-night stint in the Los Angeles area. U2 frontman Bono posted a statement Wednesday on the band’s website “We’ve lost a family member, we’re still taking it in,” Bono wrote. “He wasn’t just a legend in the music business, he was a legend in our band. He is irreplaceable.”. Los Angeles County Fire Inspector Chris Reade said first responders were called around 5:30 a.m. to reports of a man in cardiac arrest.
