Taking Names: Author Rowling gets OK for Hogwarts-style treehouses

On Thursday, a “special announcement” on its website announced the band would not play in Japan in November as planned.

“Eddie Van Halen underwent an emergency surgery for a severe bout of diverticulitis. No further surgeries are needed and a full recovery is expected within 4-6 months,” it said.

“Van Halen’s scheduled November 2012 tour of Japan is currently being rescheduled and the band looks forward to seeing and playing for their fans in 2013,” the statement added.

Diverticulitis is a condition in which pouches form in the wall of the colon, which can become inflamed or infected. It can be very painful.

Formed in Los Angeles in the 1970s, Van Halen are regarded as one of the most influential American rock bands of all time. Their eponymous 1978 debut album was a chart-topping success and spawned 13 more studio albums. The band has sold more than 80 million albums worldwide.

Van Halen’s 1984 album “1984” was the band’s high point, giving them their only No. 1 single “Jump.”

The creative tension within the band boiled over during the “1984” tour, with Mr. Van Halen and Mr. Roth falling out. Mr. Roth left the band in April 1985.

Van Halen announced a reunion tour in 2007 with Mr. Roth performing with the group for the first time in 22 years. They released their first studio album in 14 years, “A Different Kind of Truth,” in February ahead of the world tour.
