Funny story. It had to be 50 years ago but he gave a concert in Kansas City, Kansas, with Porter Waggoner, Dolly Parton, and a couple of others. Anyway the person handling the sound kept trying to make adjustment to the sound while Jones was singing. Finally Jones got mad, stopped his song and said "Whoever is handling the sound I want you to turn it up, leave it up and if I have to I'll back up!".
