That is one nice recording. I had heard that several years ago. The player states, "My own version of the jazz swing piano song from the Yamaha digital piano. I learned the chords first and then played the piano section in realtime to the bass and drums sequence."

I seem to remember finding that it is a midi sequence that comes with that keyboard and/or can be purchased from Yamaha. I am still looking for that perfect Yamaha acoustic jazz style that has a nice
walking bass for so many songs thruout the 4 variations...
