The non-singing members of Led Zeppelin apparently aren't waiting around for Robert Plant to sign off on a reunion tour and/or album. In an interview with BBC Radio, bassist John Paul Jones said he and guitarist Jimmy Page and drummer Jason Bonham "are trying out a couple of singers."

"We want to do it," he said. "It's sounding great and we want to get on and get out there." But he cautioned Plant sound-a-likes were not the goal, and that "it's got to be right. There's no point in just finding another Robert. You could get that out of a tribute band, but we don't want to be our own tribute band."

With Plant, Zeppelin reunited for a well-received one-off concert last December in London. But Plant, who has been touring with Alison Krauss for most of 2008, recently said he has no plans to work with the band again.

In recent months, Page, Jones and Bonham have logged rehearsal time together in the hopes Plant would agree to tour. Rumors have also circulated that Alter Bridge vocalist Myles Kennedy is in the running to step in for Plant.

On Nov. 4, Rhino will release a 10-disc boxed set featuring Led Zeppelin's nine studio albums plus the rarities album "Coda" in mini-LP replica sleeves with artwork from the original U.K. vinyl releases.
