The site Something Else Reviews received the news from drummer Danny Seiwell, also a member of the early-70’s version of Wings, during an exclusive interview. "Unfortunately, we just got some bad news on Henry's condition. By the time the ambulance got there, because the lack of oxygen from that period of the heart attack through first treatment, he's suffered some significant brain damage.
"Josie is very hopeful but some of the doctors, according to friends, don't think that he's going to have much of a recovery. He's going to need constant care the rest of his life. Absolutely tragic. I love Henry. He and I were very close".
