Sonisphere cancellation nixes Lambert/Queen gig - USA TODAY

The cancellation of the Sonisphere Knebworth Festival due to "unforeseen circumstances" means that Adam Lambert won't be taking the stage with Queen on the site of Freddie Mercury's last performance with the band. "While I'm sad that the Sonisphere festival has been canceled, I'm hopeful that Queen and I will share a stage again someday in the future," Adam tweeted Thursday.

Queen issued a statement on its website: "We are disappointed to hear of the cancellation of the Sonisphere Festivals as we were very much looking forward to performing with Adam Lambert and particularly as the venue was Knebworth, our last stand with Freddie. We apologise for the disappointment to all those who were looking forward to seeing us. We are working to see if we can redress the situation at some other venue."
