I'll share a few more things...
A friend of ours regretted not learning the piano as a child, so she bought one and started working on the Alfred Adult books, practicing every day, and after 2 weeks she developed wrist pain, which lasted a month. After another month, she found a teacher, who showed her proper technique, and one of the first pieces she learned was Bach's Minuet in G. She says playing that little piece she feels connected to the universe, playing the same notes that Bach did hundreds of years ago.
My wife's sister took piano lessons as a child, from a teacher who taught primarily classical pieces. In middle school, the teacher agreed to include some quality modern tunes, Mancini, Bacharach, and Broadway. In high school, her sister played in the same stage band that I did, she also played for many of the school's musical productions. Forty years later, while working as a real estate agent in West Palm Beach, a woman who had recently purchased a home asked her if she knew of someone who could play piano for an upcoming cocktail party. "I play piano", she said. And the woman offer her $300/hour to play "some nice background music", which ended up being some of the same tunes she had played in her youth. She now gets fairly regular calls to play hoity-toity soirees. Never in her wildest dreams.
