Mick Mars is denying that his illness is the reason Motley Crue may retire. Both Vince Neil and, more recently Tommy Lee have said Motley Crue may do a farewell tour sooner than later, and part of that is because Mick’s illness is making it hard for him to travel and tour. Tommy said, ” Mick has a spinal disease that’s slowly fusing his vertebrae together. It’s treatable but not curable. It’s progressively getting worse and it’s painful for him, so he doesn’t want to tour much longer.” But Mars fired back on Twitter saying, “Once again, any rumours regarding a farewell tour due to my ‘poor health’ is BS. I am doing fine. My AS has never kept me from touring. Mick’s condition is called Ankylosing Spondylitis.
