I think the most interesting thing is people with full blown Alzheimer's being able to play their instruments. Glen Campbell was a good example. He didn't know where he was doing a show, but as long as his daughter told him what song was next he plugged right along, played and sang (with help of teleprompter) and played at a high level. Tony Bennet rehearsing for his last shows. Came out of his bedroom to an introduction, his pianist playing his music. Did and intro on the piano and Tony launched into the songs one after another never missing a beat or lyric. His wife said he would just sit and stare when not singing. Quite amazing. Check it out on YouTube. I believe you can find the clip I am referring to Anderson Cooper was doing a story and was there in the room when he started his rehearsal. Just amazing stuff.

My wife asked if I had seen the dog bowl. I told her I didn't even know he could.
