Although no explanation was given for Jerry Montano's departure, the group's publicist told Headbangers Ball Blog yesterday that "personal reasons on both sides" caused him to leave.

Hellyeah drummer Vinnie Paul Abbott, who played with Bob Zilla in Damageplan alongside Vinnie's late brother "Dimebag" Darrell Abbott, told MTV in January, "I told Bob after [Dimebag was murdered] that no matter what happens, I'm gonna find a way to play in a band with him again because me and him are just bros. It was kind hard to go ahead and commit to this band without Bob being part of it, but since Jerry was the bass player it was already set in place. And Bob's been really cool and understanding. And he's doing his tattoo shop in Texas right now. And some point in the future, we'll probably play together again."

Hellyeah will launch the "Fire It Up" tour on May 20 in Baltimore before heading over to Australia and making its way to England for an appearance at this year's Download festival.

Hellyeah will take part in this summer's Family Values Tour. Also taking part in the trek are Evanescence, Atreyu, Trivium and Flyleaf, alongside headliners Korn.

Hellyeah self-titled debut album sold just under 45,000 copies in the United States in its first week of release to debut at No. 9 on The Billboard 200 chart.

A three-minute clip featuring behind-the-scenes footage from the making of Hellyeah "You Wouldn't Know" video has been posted at YouTube. The clip was shot on February 25, 2007 with director Nathan Cox in the parking lot of the Dallas, Texas stripclub owned by Vinnie Paul Abbott. The finished "You Wouldn't Know" video is available for viewing at this location.
