NASHVILLE? - Van Halen will announce a 50-date American reunion tour with original singer David Lee Roth during a news conference in Hollywood next week, sources said.

The arena trek will begin in early October.

Roth, who split from the rock group in the mid-1980s in hopes of solo stardom, will reunite with co-founders Eddie Van Halen on guitar and brother Alex Van Halen on drums. Eddie's teenage son Wolfgang will sub for Michael Anthony on bass.

A proposed summer amphitheater tour by the group never got off the ground, with Eddie Van Halen entering a rehabilitation facility for undisclosed reasons in March.

In the months since, the guitarist has been seen publicly looking healthy and fit.

Van Halen last toured in 2004, with Roth's replacement, vocalist Sammy Hagar, grossing nearly $40 million, according to Billboard Boxscore.
