Do you know ALL the words to popular songs?

[Rain Man]

I'm not talking about songs like Happy Birthday or Jingle Bells. I'm talking about rock and roll, or country, or pop, or other songs like that.

I was thinking about it today. I have a lot of songs that I like and listen to a lot, but the words apparently go in one ear and out the other. If you ask me to sing "Thunder Road" or "Fred Jones Part 2", or "Piano Man", I can't do it without humming some of the parts. And I've heard these songs a zillion times.

I'm not sure that I can sing a single song from start to finish. If you asked me, I would say yes, but if you tell me to do it, I don't think I can.

So think about it for yourself. Can you sing any/some/many songs from start to finish without the music behind you and without singing along with the singer? If so, prove it.
