Fun, reminds me of the enjoyment I had listening to the Swingle Singers doing a cappela Bach in a jazz mode.
A vignette, when I was a new college student (fifty years ago now) I had a party at my home and there was a high school student there complaining about the music (Bach's Brandenburgs), "who's this?" he asked. "A new jazz group led by a guy called Joe Bach", he listened then and liked it. I've always rather thought that Bach would have enjoyed jazz, the combination of structure and improvisation. Best, Jon
