A source familiar with the tour who was not authorized to speak publicly confirmed that some of the band's long-scheduled performances this summer will be postponed. The group's website lists tour dates through June 26.
Dozens of additional shows had been planned and there was no immediate reason given for the cancellations. Representatives of the band and AEG, which is promoting the concerts in some regions, did not respond to messages from The Associated Press on Thursday.
A Van Halen concert is scheduled for July 11th at the Wells Fargo Center.
