True story about Dolly Parton:
I think it was 1975, and she had just gone solo as an artist after being with Porter Wagoner. She had a concert scheduled for the Heart O' Texas Colosseum in Waco. It seated several thousand people, but only about sixteen people, including me, showed up.
We were all gathered around the stage, and I heard her talking to her road manager. He was telling her to just refund the ticket money and they could pack up and go to the next town. She told him these people paid for a concert, to give the band the night off, leave one guy for security, and she'd take care of it.
She got a bar stool and her acoustic guitar, gathered us around in a circle, and did a 1 1/2 hour concert (no microphone, she was close enough we could all hear her perfectly,) then signed autographs for all of us. It was the best concert I ever attended.
Couple of notes: in person, she sounded just like on the records. She can REALLY sing and she can REALLY play guitar.
