I personally found this quite moving, it even brought tears to my eyes, as I have seen my mother in law suffer from Alzheimer's.

When I used to perform for for seniors I saw first hand how therapeutic music can be.

Sure Tony is not in his prime, but I think he's doing quite well for his age especially considering his condition. Music obviously still brings much joy to not only him but also his fans as well. Lady Gaga strikes as very caring too.

Keep doing music !
