During the intro I was hoping for Tuxedo Junction, oh well. Not the most exciting arrangement of Mack the Knife, since the build-up of lyrics, music and key changes is what really makes that song, but in whole a very nice job. It is great to see someone actually play and not rely on accompaniment tracks; nice pedal work from what I could tell. The only negative comment, other than the excessive reverb (seems to be typical of the Tyros) is he needs to remove the volume pedal altogether or learn how to not tap his right foot to the music. A very common mistake that non-organ players make is pumping the volume pedal like that. Surprising since this fellow knows his way around bass pedals leading one to believe that he is an old school organist.
