Is the foundation for a better life commercial with the little boy playing the piano on stage a true story as it indicates and if so where can you find it?

Answer 1

No, there's no proof it actually happened. From truthorfiction.com:

There are various versions of this story.

In some of them, the boy plays "Twinkle, Twinkle, Little Star."

In this version, it is said the boy played Chopsticks, a simple little tune that every child who has had access to a piano seems to have learned how to play.

There is no evidence this ever happened, however.

Ignacy Jan Paderewski (1860-1941) was a Polish pianist who gained world wide fame and was very popular in the United States.

Paderewski experts say the story may have been inspired by a poster during World War II that promoted a meeting in support of the Polish Relief Fund.

Paderewski is said to have organized the meeting.

The poster included a sketch of Paderewski next to a boy at the piano.

The boy was carrying his belongings wrapped at the end of a stick and was called "Johnny the Wanderer."
