BLACK SABBATH guitarist Tony Iommi has posted the following year-end message on his official web site:"What a year! Certainly not the one I was expecting. "Thanks to you all for your massive help and support; it was very encouraging. "I'm still working on the [new BLACK SABBATH studio] album and managed to play three shows. Not bad given the news a year ago. "I'm looking forward to next year, seeing what you think of the record and touring as much as we're able. "My best wishes to you all. I hope you have a great Christmas and New Year, most of all, stay positive." Iommi underwent chemotherapy treatment earlier in the year after being diagnosed with lymphoma at the end of 2011.
