Geezer Butler recently spoke to The Pulse Of Radio and said he thinks that Sabbath already have a head start on a new record, explaining: "We've still got four tracks left over from '13' so maybe we'll fill in the other four or five tracks and put out another album — if it's right. We wouldn't do it just for the sake of it, or the money or whatever. But yeah, maybe."
Vocalist Ozzy Osbourne added: "I never say never. I never thought after 35 years I'd [be back with Black Sabbath], have a No. 1 record and a sold-out tour."
Tony was diagnosed with lymphoma in January 2012 and completed his treatment in March. He is now awaiting an update on his condition.
"I'm at a stage now where I have no support, which means I have to see whether the cancer is coming back or if it's still there or what," he said. "I just don't know. It's a bit of a worry. After we finish this tour I'll go in and have a scan, so we'll see what that shows up."
"But the show at Hyde Park will a great way to end the European tour," he added. "It has a really great bill, with a really good mix of people. I think it'll be special."
And it was indeed special and we will be publishing our review of Friday's event as soon as our reporters sober up.
