In perhaps one of the strangest pairings in recent memory, former Van Halen frontmen David Lee Roth and Sammy Hagar will hit the road together on this summer's co-headlining Song For Song, The Heavyweight Champs Of Rock'N'Roll tour. The 21-date run will kick off May 29 in Cuyahoga Falls, Ohio, and last through a June 29 finale outside of Seattle.

According to Hagar's official Web site, he and Roth met earlier this year for the first time and he was "blown away at how well they got along together." He added, "if [the tour] happens, this would have to the party of a lifetime."

The trek will follow a slate of May headlining dates Hagar has lined up with his band, the Waboritas. Those shows kick off with a May 5-7 stand at the Fillmore in San Francisco. Also on Hagar's calendar is his annual weekend "Meltdown" festival at his Cabo Wabo Cantina in Cabo San Lucas, Mexico.

Outside of the tour with Hagar, Roth's only other scheduled appearance is a May 3 performance at Atlanta's annual Music Midtown Festival. For an update on Roth's sound, fans can visit his official Web site, which at deadline featured only a Quicktime video of the artist performing an upbeat bluesy-rock song with his band.

After more than a decade, during which Van Halen became one of the world's most popular rock bands, Roth exited the fold after a falling out with the other members. In 1985, Hagar -- former lead singer of the band Montrose and a successful solo artist -- joined Van Halen and helped lead its second incarnation through its biggest commercial triumphs.

Following Hagar's acrimonious 1996 departure, former Extreme singer Gary Cherone filled the position, but stuck around only long enough to record 1998's disappointing "Van Halen III."

Roth has previously reported that he was working with guitarist Eddie Van Halen on some new music, but to his chagrin nothing concrete had come of the sessions. The notoriously private guitarist later disclosed that he was battling cancer.

Last year, Van Halen left its longtime home at Warner Bros. Records. In February, the group's attorney, Alan Mintz, told Billboard the band was "weighing all the options and seeing what the future brings, [but] it's still premature to say where the band will go." He says the band will "seriously consider" major-label offers, but that such a move isn't a given: "These are interesting times."

In other news, Van Halen bassist Michael Anthony recently noted on his official Web site the he and Hagar recorded a pair of songs with Journey guitarist Neal Schon and drummer Dean Castronovo. The project has been dubbed Planet Us and the songs the band recorded are titled "Vertigo" and "Peeping Through a Hole," the latter of which Anthony described as "a high energy song that will almost leave you p***ed off by the time you're done listening to it because it's so intense."
