Launch Radio Networks reports: Could VAN HALEN's performance at the Rock and Roll Hall of Fame's March 12 induction ceremonies be in jeopardy? A source has told the Rocky Mountain News that the planned performance might not happen, presumably due to tensions over the postponement of the group's 2007 reunion tour with original vocalist David Lee Roth. The news of the tour's "indefinite" delay broke on Tuesday (February 20), with unnamed sources confirming the story to USA Today and Pollstar, among other media outlets. According to MelodicRock.com, the proposed 40-city trek is not canceled, but put on hold until all the parties involved can iron out their issues.No official statement has been released regarding the tour's postponement. The jaunt was reportedly going to start in Las Vegas in late April, with tickets possibly going on sale this coming weekend. Janie Lisewski, a former adult video publicist who is now Eddie Van Halen's girlfriend and spokesperson for the Van Halen family, issued a press release on February 2 confirming that the tour was on. But her statement was apparently issued before any contracts were signed and without the endorsement of Roth or VAN HALEN's management. The tour would be Roth's first with the group in 22 years, and would also feature the debut of Eddie Van Halen's son Wolfgang on bass, replacing original bassist Michael Anthony. The Rock Hall induction at New York City's Waldorf-Astoria Hotel will also include Roth replacement Sammy Hagar. Whether the band would perform with both Roth and Hagar at the event was yet to be determined. A greatest hits collection taken from Roth's years from the band is also now officially "on hold," a record label spokesperson told Launch.
