Billy Joel often changes the words to his songs in concert. For example:

Captain Jack

And you look so Rod Stewart from your hair down to your toes

It's Still Rock and Roll to Me

Should I try to be a straight A student, if you are then you drink too much.

Scenes from an Italian Restaurant

Things are OK with me these days,
Got a good job, got a good office,
Got a new wife on the cover of Life,
And the family is fine.

Only the Good Die Young

You didn't count on me, when you were counting on the ideology.

I Go To Extremes

I don't know why I go for ice cream.

Pressure

You use to give me hemorrhoids,
But even you cannot avoid, PLEASURE!

The River of Dreams

I don't know why I go drinking at night,
When I'm tired and I don't want to sing anymore.
