That was really just intended for
@It Aint Necessarily So, but as you've responded...
It was obviously a sound recording that had been placed on YouTube, so I wouldn't expect video, and in any case the lack of video had no relationship to the quality of the music.
It was also probably a live recording that did not have the advantage of studio editing. I also noted the imbalance in voice and guitar. If you follow the link to YouTube (click on it) you will see two more recordings, which are better in that respect. His wife's voice is very good in my opinion, always on key, good tone and singing the notes correctly for the song.
I play guitar at a low level and would give a lot to play half as well as he does.
But you're entitled to your opinion of course.
