Here is an interesting story:

In a 2007, violinist Joshua Bell went busking in an experiment to see if the public would recognise one of the finest talents in the classical world.  Joshua Bell is one of the world's greatest violinists.  He's musical director of the Academy of St Martin in the Fields, a soloist and former child prodigy, known the world over for his amazing playing and floppy barnet.  Seriously, he's proper famous. 

In 2007, when he stuck a baseball cap on his head and rocked up at a Metro station in Washington and began to busk, you'd expect at least some of the passers-by to stop, say "crikey", and pop some money in Mr Bell's violin case.  In fact, top-notch conductor and fellow famous person Leonard Slatkin predicted that "out of 1,000 people, my guess is there might be 35 or 40 who will recognise the quality for what it is. Maybe 75 to 100 will stop and spend some time listening." He also predicted he would make $150. 

So what happened?

Hardly anyone stopped. In fact, out of 1,097 people that passed Bell by, only 27 gave any money, and only 7 actually stopped and listened for any length of time.

And how much did he make? The violinist who can command thousands for each concert performance on the greatest concert stages in the world?

$52.17

Which is not very much. And $20 of that was from the one person who did recognise him.
