From RobertPlant.com:
Robert Plant and Alison Krauss are currently touring the USA on the last leg of their 'Raising Sand' tour. They played a benefit concert in Oklahoma City for victims of Hurricane Ike last Friday; Austin,Texas last Saturday and tomorrow they play Portland, Oregon before finishing the tour in Saratoga, California on October 5th.So that is that, it appears. Either Jimmy Page, John Paul Jones and Jason Bonham go out with someone else, or the Zeppelin dream is over for now.
After those dates, Robert has no intention whatsoever of touring with anyone for at least the next two years. Contrary to a spate of recent reports, Robert Plant will not be touring or recording with Led Zeppelin. Anyone buying tickets online to any such event will be buying bogus tickets.
“It‘s both frustrating and ridiculous for this story to continue to
rear its head when all the musicians that surround the story are keen to get on with their individual projects and move forward,” Robert Plant said.
“I wish Jimmy Page, John Paul Jones and Jason Bonham nothing but success with any future projects,” he added.
