No Gary, I am sure others noticed it as well, and I doubt that anyone expected him to have a full orchestra in the street with him ...
Most of us were just concentrating on his voice, and if you notice, he is constantly rotating his seat so he sings to the entire audience, and his back is to the equipment most of the time, so he is not 'stuck on the screen reading lyrics' ...

There is no way I would put him in the generally accepted connotation of a "Karaoke singer" ...

Sing on you singers ...
