As a classical singer, he has sung roles in opera, operetta, oratorio and given classical recitals, as well as lending his versatile voice as an overdub for less vocally gifted artistes on stage and screen. As a pianist he has recorded movements from piano concertos by Grieg, Tchaikovsky, Rachmaninov and Schostakovich, as well as accompanying many classical artistes in concert, recital and recording, including Marilyn Horne, Marilyn Hill Smith, Linda Ormiston, Richard Morrison, Patricia McMahon, Cheryl Forbes, Rosalind Sutherland, Elizabeth McCormack and Sean Rea. As time passes, Gordon's input to the orchestral world is on the increase, with hundreds of arrangements, orchestrations and compositions he has written for leading orchestras and artistes, to be performed - often conducted by himself - for concert or broadcast.
Gordon is proud to be an active member of The Scottish Showbusiness Benevolent Fund and a full member of the British Ring of the International Brotherhood of Magicians. He also owns the only art deco custom-built concert marimba that Boosey and Hawkes ever made, which frequently appears onstage with him.
