Black Sabbath guitarist Tony Iommi has confirmed that his band's decision to head out on a farewell tour is down to his own health concerns from his cancer. "I can't actually do this anymore", he told the Birmingham Mail. "My body won't take it much more. All the travelling involved in Sabbath tours increasingly takes its toll. That's why we're going out on one last tour, to say our farewells. And then it very definitely is the end, we won't be doing it again". In January Iommi admitted he was unsure how much longer he will live, saying it could be anywhere from one year to 10 years - he was diagnosed with cancer (Lymphoma) in January 2012.
