Franz, John, Johannes & .... Jelly Roll?!

At this point in the book, the doctor of the novel's title (Jim Parsons) has been whisked far into the crazy future of 2405, where his skills as a lifesaving physician are in fact deemed criminal. The following bit is tossed in to demonstrate just how topsy-turvy this far away future is:

Inside the house, in the living room, Amy sat at the harpsichord. At first the music did not seem familiar to Parsons, but after a time he became aware that she was playing Jelly Roll Morton tunes, but in some strange, inaccurate rhythm.

“I got to looking for something from your period,” she said, pausing. “You didn’t happen ever to see Morton, did you? We consider him on a par with Dowland and Schubert and Brahms.”

Parsons said, “He lived before my time.”

“Am I doing it wrong?” she said, noticing his expression. “I’ve always been fond of music of that period. In fact, I did a paper on it, in school.” -- Philip K. Dick, Dr. Futurity (1960)
