And I value your opinion John, but if you didn't recognize the song from the intro and first 'play-through', then I have to assume that you don't know the song. The entire first chorus was about as 'straight' as one would play a jazz tune. I also ended it the same way. I've provided a few examples below to help familiarize you with the tune (along with a tutorial on the chord changes). Enjoy. Remember, 'jazz' represents freedom; freedom to interpret, express, play, a tune any way you like (within commonly accepted guidelines). That's probably why there are so many sub-genre's of jazz. That's why no two jazz musicians will ever play a tune exactly the same way. I encourage you to listen to as many of the examples below as you can. We can all learn from listening to others. Have a great day.
