Van Halen has rescheduled tour dates postponed earlier this month when guitarist Eddie Van Halen was undergoing tests for an unspecified medical condition.

The band will proceed on April 19 in Las Vegas and play 20 shows in all, with the last date set for June 2 in Grand Rapids, Mich. Tickets for the band's previously scheduled dates will be honored.
