I ain't Jeff, I ain't Jeff

The story:

I was walking out of the Rolling Stones concert in Norman Oklahoma and over-heard a couple having a discussion. The lady was quite drunk mad because she didn't get to hear her favorite Stones song. He boyfriend asked which song it was. She said, "I ain't Jeff." He looked puzzled and asked her to sing it because he had no idea what song it was. She began to sing "I ain't Jeff, I ain't Jeff but you can't say I didn't try." Everyone within ear shot started laughing hysterically and he just shook his head and told her that they only had a certain amount of songs they could play in a show.
