     Once there was a piano player in a bar(酒吧). People came just to hear him play. But one night, a

lady asked him to sing a song. "I don't sing,"said the man.

     But the lady told the waiter, "I'm tired of listening to the piano. I want the player to sing !"

     The waiter shouted across the room, "Hey, friend! If you want to get paid, sing a song!"

     So he did. He had never sung in public before. Now he was singing for the very first time! Nobody

had ever heard the song Mona Lisa sung so beautifully!

player in a no-name bar. But once he found, by accident, that he could sing well, he went on working
