"My one and only purpose during this time has been to get back on stage," he continued. "My singing voice is fine. However, after three operations, stem cell treatments, endless physical therapy sessions, and most recently groundbreaking Cybernics (HAL) Treatment, my body is still physically weak."
He added, "I am honestly humbled by the way you’ve all patiently held onto your tickets for all this time, but in all good conscience, I have now come to the realization that I’m not physically capable of doing my upcoming European/UK tour dates, as I know I couldn’t deal with the travel required. Believe me when I say that the thought of disappointing my fans really F---S ME UP, more than you will ever know."
"Never would I have imagined that my touring days would have ended this way. My team is currently coming up with ideas for where I will be able to perform without having to travel from city to city and country to country,"
