What happened to Greek guitarist Petros Nicolaou?

<FONT SIZE="+1">Petros (Peter) Nicolaou</FONT> was a Greek guitarist I knew in Chicago and later in New York City in 1955-1958. He also wrote for a Greek newspaper in the United States. I would very much like to know what became of him. He came to Chicago in November 1955 to play at clubs during Greek month. Also with him was a very famous Greek <U>accordion player</U> whose name was something like James Fransicone. Any information you have about either of these old acquaintances would be deeply appreciated.
