First, welcome ATT!!!!
Second, funny you should mention Glen because that was actually the first thing I thought about when they mentioned former members. He did a great job also but I believe he was in the early stages of the disease at the time her performed there. Fact is, none of us know to what extent Randy has been affected by the disease. I've had 2 friends that have lost their parents from it and it was ugly, ugly, ugly, especially toward the end. They become childlike after awhile. They do tend to remember things from long, long ago but can't remember what they had for their last meal or see someone and recognize them and then 5 minutes later not know who they are. So very sad.
I guess time will tell for Randy.
