The band canceled a series of shows on their summer European festival tour following doctor's orders after Lemmy suffered a haematoma (where blood collects outside of a blood vessel) and needed to address the issue; the bassist had previously been fitted with a defibrillator because of heart problems. "I can still stand at that mic every night and play my songs," explains Lemmy. "I'm getting better. By the time the tour comes around I'll be ready."
