In a statement Charlotte St. Martin, executive director of The Broadway League, said, "George was a passionate lover of all things theatrical and was pivotal in helping revive the road as major national platform for Touring Broadway. Our thoughts are with his family and friends." Mr. MacPherson served in leadership roles at Masque Sound, a company that provides sound systems for the majority of Broadway musical productions and concert attractions; Edemol Theatre Productions; ATP Dodger Productions; and his own general management office.

He managed many national tours, including Hello, Dolly! starring Yvonne DeCarlo, and served as the personal manager to humorist Victor Borge and entertainer Harry Belafonte. In 1993 Mr. MacPherson became the second recipient of The Broadway League's Distinguished Lifetime Service Award. He received three Helen Hayes Awards for his productions, the National Touring Council Award for Outstanding Service and The Metal of Merit from Her Majesty Queen Elizabeth II for his contribution to the Arts in Canada on the occasion of the 25th Anniversary of her Accession to the Throne.
