The lady in front of me had a little girl about the same age. The mother asked me how my son would know that song. I shrugged. "Must be from Guitar Hero." (Note: Proud Parent Moment 417)
Then "Take Me out to the Ball Game" was played over the loudspeaker. Lots of people sang along including the little girl in front of us. My 5 year sat silently in his chair.
Guess they don't put that song on Guitar Hero.
