"I thought anybody who could have that emotion that deep and pure would always take care of me and always love me," said Joni.
That was the first of dozens of songs Steve would write for Joni. A song for every occasion, every mood, every memory. In February, they will celebrate 50 years of marriage.
Steve's music has created a soundtrack of their unforgettable love story, but that story hit a snag several years ago.
Steve was diagnosed with early on-set Alzheimer's, and the music he wrote and used to know so well, is slipping through his fingers.
At the piano one afternoon, Steve groaned, as he stumbled on melodies he once played from memory nearly every day.
"Darn, see what I go through," he said, as he played a wrong note again.
He was fighting a fog in his brain.
"I could hear all the music in my head and heart, but I couldn't get my brain to connect to my fingers," he said. "That was frustrating. Then I realized I might be going down the same road my mother did."
Steve and Joni took care of his mother in her final years. They saw first-hand what lies ahead. Steve, 69, was diagnosed with early on-set Alzheimer's.
"It was devastating," said Steve.
He had to quit his job as a software designer. The disease was stealing his memory -- and his songs.
He never thought they were good enough to share and he never wrote most of them down.
"I never thought I'd have to worry about them going away," he said.
Music he composed for his daughters, and played them nightly as lullabies, was slowly fading away.
"It hit me like a tidal wave that not only would I be losing my daddy, but the soundtrack of my childhood," said his daughter, Melissa Goodwin.
