Jack - as far as I am aware I have not accused anybody of lying.
I have presented my opinion the best I can based on my own experiences as a singer and by passing the information we have recorded from field singers, who I believe are the experts - not the holders of City and Guilds Certificates.
The only 'standards' I have asked for are basic ones required of anybody who chooses to perform the work of others publicly, if they are going to show any respect to that work.
It is your posting that exudes arrogance and insult - have a nice day.
