What Art Thieme said both times.

Singing an old song your way, and even changig the words and the tune to fit teh way you sing, that is fair enough, and it can stand or fall on its own merits.

But messing around with what people sang and played is different. When it's a matter of tryoing to make it sound more lkke it really sounded like, by taking out distirtion introduced by the recording process, that is one thing - but : "They tampered with Almeda Riddle's vocal in one case, "correcting" her original failure to adhere to a regular meter." That's just disrespectful. And the idea that singing has to always "adhere to a regular meter" is musically and culturally illiterate.
