Alzheimer is affecting his memory --- but when a song comes on the radio?!

Since 2013, when Ted was diagnosed with Alzheimer's disease, his memory and mental health have deteriorated more and more.  Ted, who was a professional singer for Butlins Redcoats, a famous chain of family entertainment centers in England, now can barely recognize his family members and is often prey to attacks of rage.

Ted's son decided to raise awareness about this disease among friends and the public in general, by filming his father, in the only moments when Ted is lucid -- which is while he is singing.
