Brookhaven musician Blake Scafidel entertained a crowd of about 50 who gathered in front of the Downtown Music Academy at noon Friday at the unveiling of the city’s first street piano. Scafidel and his wife, Carrene, who is also a musician, have loaned the family piano to be kept on the sidewalk and played by the public. Don Jacobs hand-painted the instrument with an Elton John/Rocket Man theme.
