Dennis Sheehan, U2's longtime tour manager, was found dead in a Los Angeles hotel this morning. According to TMZ, he was found early this morning, just hours after the band kicked off a five-night stand at the city's Forum.

Sheehan, who was in his 60s, was reportedly found unconscious in his room at the Sunset Marquis Hotel. TMZ reports that paramedics were called around 5:30AM for an apparent cardiac arrest, and Sheehan was pronounced dead on the scene.

U2 have been managed on the road by Sheehan for more than 30 years, and was on hand for their sold-out show in Los Angeles last night. According to the Irish Mirror, sources close to the group say the four remaining shows are still on the schedule: “Everyone who works with the band is heartbroken. This has come as a huge shock, but the view is that Dennis would have wanted the show to go on. But that could be subject to change.”

The Mirror notes that in an interview, Sheehan recalled how he got his gig working for one of the world's biggest bands. “U2 were looking for a tour manager, they had two albums out and they were about to bring out the War album," he said. "I joined them and we haven't looked back ever since. “After two weeks on the road, they approached me and said, "Can we keep you?"

In 2008, Sheehan was awarded the Parnelli Lifetime Achievement Award , which is referred to as the "highest honor for live event professionals." His career, which started in the '70s, also included stints with Led ZeppelinIggy Pop and Lou Reed.
