About 42 years ago my mom bought a wonderful baby grand piano from a friend. Five or six years later I learned to plunk out the blues in key of C, so when my mom ran out of house for the piano, she let me take custody. I've bugged my kids with the same blues in the same key for as long as they've been alive. (It's endlessly entertaining to me, anyway.)
Tonight, the old piano finally got a real workout-- and I was there to hear it.
