A legendary rock band that has sold over 150 million albums worldwide has announced a farewell world tour beginning this October. The tour will span five continents over 18 months, with 80 arena and stadium dates planned across North America, Europe, Asia, Australia, and South America.

The band, whose career spans four decades, said the decision was bittersweet but that they wanted to say goodbye to fans on their own terms while they can still perform at the highest level. Tickets go on sale next month, and fan club members will receive priority access to presale codes.
