My mom, for example, would stop whatever she was doing, or wake up from a nap to listen to Frank Sinatra, Nat King Cole, Tony Bennett or Peggy Lee even on the last day of her life. She would sing the lyrics in a soft voice and remember it all from dances and concerts she went to in the late 1930s and later! The music inspired her, made her happy, and enriched her life. Same with your mom and dad? I saw it happen with dozens of very old people. There were even a few men in their 90s who had played in Big Bands 60 or 70 years ago.
Don’t they call music the Universal Language?
