Sources tell Billboard.biz a contract could be signed as soon as today for
Live Nation to produce a 40-date amphitheatre tour by Van Halen this summer,
with original frontman David Lee Roth back in the fold for the first time in
more than 20 years.

As previously reported, guitarist Eddie Van Halen's 15-year-old son Wolfgang has stepped in for original bassist Michael Anthony in the new incarnation of the group, which also features drummer Alex Van Halen.

Van Halen last toured in 2004 with vocalist Sammy Hagar, grossing nearly $40
million, according to Billboard Boxscore. Hagar refused to collaborate further with Eddie and Alex Van Halen after the tour's completion ("I don't get along with Eddie anymore, and that's all there is to it," he told Billboard.com in August 2005), although he has consistently played live with Anthony in recent years. The warring factions may wind up meeting in public in March when Van Halen is inducted into the Rock and Roll Hall of Fame.

"I see it absolutely as an inevitability," Roth told Billboard.com last May of a potential reunion with his ex-bandmates. "To me, it's not rocket surgery. It's very simple to put together. And as far as hurt feelings and water under the dam, like what's-her-name says to what's-her-name at the end of the movie 'Chicago' -- 'So what? It's showbiz!' So I definitely see it happening."

Hagar recently told Billboard.com he was concerned Eddie Van Halen was asking too much of his son to have him join the band and promptly perform in front of thousands of people every night.

"That's a lot of pressure for Wolfie. Just 'cause he's Eddie's son doesn't
mean he can go out and play in arenas and perform and entertain an audience
for two hours," he said. "I would love to see Eddie and Alex get behind
Wolfie, with a kid of his age singing, and produce the record for him and
help him launch a career. I'd rather see it go that way than come out and
say 'Wolfie's the bass player in Van Halen and maybe singing, too.' Van
Halen's got way too much history to have that put on him."
