It looks as if Van Halen may have taken on more than they could handle.

A source from the band's camp has told Billboard that it has nothing to do with illness or (as some expected) internal strife, but simply that the band is worn out and needs some time to rest and recuperate.

"[The band is] doing great with ticket sales. They're not fighting. They're just burnt and they want to take some time off," says the source. "They got so excited and everything was going so well, they said, 'let's add more dates,' and I don't think they realized how tired they were. That may not sound like the truth, but it is."

The band has fifteen more shows before starting their mini-vacation with a minimum of thirty afterwards, all of which are being pushed out from their original dates between June 26 and September 25.
