What a great story, Jed, and how great that you can still enjoy your parents. Music is one of the few good things I got from my folks, and my best memories are of singing 30's and 40's tunes with them in the kitchen while making dinner. And it is true that music memory is longer lasting than any. In the convalescent home where I play there are people who seem entirely gone, no longer communicating, but can join in on You Are My Sunshine...it's the one sone everybody seems to know.
