Last December, the impossible happened: the remaining members of Led Zepelin reunited for one night only at London’s O2 Arena. Since the gig in honor of Atlantic Records founder Ahment Ertegun, seemingly an endless amount of rumors have circulated speculating that the band would embark on a full worldwide reunion tour. Despite the gig’s massive success, frontman Robert Plant was too busy and having too much fun supporting his collaborative release with Alison Krauss, Raising Sand, to reunite with his mates. Their tour lasted through this past fall but Plant denied he would reunite with guitarist Jimmy Page, bassist John Paul Jones, and drummer Jason Bonham (son of the late John Bonham), after it. But what about a tour without Plant at the helm?
