No news yet but expecting 40 worldwide dates celebrating 40 years in the business. I think the band will do this tour and that will be it. I can imagine all dates will be outdoor venues. Same next year for Sabbath as well - two great bands bowing out in style in the same year.
It's rumored AC/DC to headline Glastonbury next year. I remember the organizer giving a little clue saying "a English band but not living in England anymore" - so that would rule AC/DC out of the equation - Sabbath to headline Glasto anyone?
