You are so right on Preacher. Melallica wouldn't know what to do anymore with a real metal band on the bill with them! One roar from Chuck Billy and the crowd would be Testament fanatics for life.
Well... chemotherapy is *very hard* on the body! Chuck had liquid chemo, a/k/a poison, pumped into him 6 hours at a time, along with injections of 2 different drugs which contained steroids. This makes the cancer patient put on weight, causes serious bloating AND lose all their hair!
The side effects have been subsiding, and Chuck's hair is growing back. He's going through physical therapy, has lost the weight, and is getting back to his old self again .
