I found it very enjoyable and well constructed and careful to keep its appeal broad to those who know the music intimately and those experiencing the songs and singers for the first time. Generally, the speakers were well chosen. There were a few minor things that I didn't like about it but they they were well outnumbered by the things that I enjoyed.
The main message the programme seemed to have was 'This is the music and song of sincerity' and that is one of the elements that attracted so many of us to this music,
