You may have noticed the photo I used last Saturday to illustrate my story about my ancestry. It was a photo of my maternal grandfather playing some sort of instrument. I jokingly referred to it as a recorder, but of course I know it wasn't. That doesn't mean I do know what it is, because apart from a tuba and a saxophone I am a complete brass-instrument-ignoramus. So, when Millie and Walter commented that they thought it was a tuba, I felt I could be quite certain in my dismissal of that notion.
And then, on Sunday, I came across another photo of my grandfather with a musical instrument. And by the looks of it, while he was on his way to or from practice. Could this be the tuba??
