While Zep Glastonbury reunion rumor put to rest, Robert Plant and Jason Bonham align

The band replacing U2 at the Glastonbury Festival next month is going to be Gorillaz, the festival announced today. U2 canceled the Glastonbury date as well as North American tour dates due to the physical condition of singer Bono's back.

So much for reported rumblings that U2's replacement might be a reunited Led Zeppelin.

That's one less possible topic of conversation tomorrow morning when Jason Bonham and Robert Plant appear together on "The Paul & Young Ron Show" for whatever reason. Since their booking, originally slated for yesterday morning, was accompanied by a press release that got a fair amount of traction on the Web, they must have some kind of an announcement.

Yesterday, a publicist for Jason Bonham's Led Zeppelin Experience confirmed Plant and Bonham's joint radio appearance as well as the timing of it -- now scheduled to take place at 8:20 a.m. on Thursday, May 27 -- but said she would be finding out what it was all about while the chat takes place live.

"The Paul & Young Ron Show" airs live weekdays between 6 and about 10 a.m. on several terrestrial radio stations in Florida. Big 105.9's Web site streams the show live.
