'Piano Man' plays for refugees at Polish border

STORY: He was joined at the keyboard by a Ukrainian woman played 'We Are the Champions' by British rock band Queen. Speaking a few words in English and making gestures, the woman suggested she had crossed from Ukraine and had not slept for three days.

Martello, a 40 year-old Italian who lives in Germany, also performed John Lennon's peace anthem 'Imagine', which some consider one of the greatest songs of the 20th Century.

Martello's trademark is the giant white peace sign painted on the side of his piano. He says his aim is to use music to promote peace.
