The Sammy Hagar-fronted Van Halen tour is on a sell-out track.

On Saturday (April 3), the first day of ticket sales, shows in Boston, New York, St. Louis and Las Vegas sold out. Due to high demand, dates were added at the Centrum Centre in Worcester, Mass.; the Continental Airlines Arena in East Rutherford, N.J.; the Saavis Center in St. Louis; and the Mandalay Events Center in Las Vegas.

This road trip is the first time Hagar will perform with Eddie Van Halen, Alex Van Halen and Michael Anthony in more than nine years.

Van Halen's career has spanned 25 years and multiple hit singles and albums.
