Friends of Toronto music legend, “Professor Piano” plan to step up the search for the missing musician.

80-year old Scott Cushnie has been missing for over a month. He was last seen east of downtown Toronto.

Friends are organizing a search for the musician who is legally blind. They’ll gather today outside his apartment in the King East, River Street area, to expand their search and put up more posters.

Cushnie has played with such greats as Robbie Robertson and Aerosmith, but is best known for his work with the “Rocking Deltoids” and the “Canadian Aces.”
