Black Sabbath guitarist Tony Iommi recently suggested that the band's upcoming performance at British Summer Time festival at London's Hyde Park on July 4 might be their very last.
The show marks the final date of Sabbath's summer 2014 tour, as well as the final date of their concert itinerary in general.
"It could be the last ever Sabbath show," Tony told Metal Hammer. "I don't want it to be, but there's nothing really planned touring-wise after that show, so for all we know that could be it really. To be honest I don't want to be touring to this extent too much longer, because it makes me feel so bad."
Discussing cancer he's been battling since January 2012, the guitarist confirmed being in a stressful position of just waiting for further results. "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 scan, so we'll see what that shows up," Iommi continued.
Rounding it up on an optimistic note, the guitar god concluded, "But the show at Hyde Park will a great way to end the European tour. It has a really great bill, with a really good mix of people. We haven't made any specific plans as the gig is a way off yet, but I think it'll be special."
The show itself will see Sabbath headlining the night above Soundgarden, Faith No More, Motorhead, Soulfly and Wolfmother at the festival's main stage. Ticket pricing and additional info here.
