Here's a lovely bedtime story narrated by Morgan Freeman. WARNING: EXTREMELY NSFW!!!
A deliberate parody
from 2007, which removes a little of the weirdness factor, but still pretty weird.
Full movie--under forty minutes--below.
Listen to the famous elegant phrasings of Jo Stafford
in one of her typically stylish excursions. "Admired for the purity of her voice, she originally underwent classical training to become an opera singer," it says at the link.
Now listen to her do hillbilly. I guess good training allows mastery of any mode.
