Former GUNS N' ROSES star Duff Mckagan has offered the strongest hint yet that Led Zeppelin will be embarking on a world tour - because his band Velvet Revolver have been signed up to support them. The Stairway To Heaven hitmakers reformed in December (07) for a one-off tribute concert in London after a 27-year absence, and despite massive demand, the band have refused to confirm whether they are planning any more live dates. But MCKagan is sure the veteran rockers will embark on a series of live dates across the globe once frontman Robert Plant finishes his current project with Alison Krauss. And the 44-year-old bassist has revealed Velvet Revolver have landed the prestigious role of opening the show. He tells Blabbermouth.net, "I understand that we have it, although I imagine there will be plenty of bands prepared to kick and punch us out of the way for the privilege!" The Cult are also said to be in the running to join Velvet Revolver in a support slot after lead singer Ian Astbury told the audience at a U.S. gig they would be playing with Led Zeppelin on a possible reunion tour later this year (08).
