Sean... what a brilliant story.

I was mother to one of them there authenticity snobs. My daughter Andie was in the medieval SCA and took it all a bit seriously. "Mom, Did you research that headress?" "Mom, if you can't pronounce the Gaelic words correctly in this song, please don't sing it." Mom, your latin pronunciation is terrible."
The film Elizabeth was a travesty because "the costumer did not research Tudor textile design properly, the dance Lavolta was ridiculous and wrong and the film closed with Mozarts's Requeiem.... what's up with that? Didn't the film have a historian?"

She was still a delight if a bit OTT.

I guess I get some quality check looks now and then specially when I sing Summertime and Georgia On My Mind, because I do 'em different than the norm.
