GUS principal Bert Sullivan guided Trevor Groom's euphonium playing from boyhood.
Trevor and Bert's relationship blossomed when Trevor left the Kettering Citadel Salvation Army Band to take over the GUS top euphonium chair from Bert in the 1960's.
Right from the start, Trevor made an impact, starring in the 1964 National-winning band and his reputation subsequently took him around Britain and to the United States as a soloist.
Composer Joseph Horovitz wrote and dedicated his Euphonium Concerto to Trevor, who had by then become an established soloist.
Although Trevor returned to the Kettering Salvation Army Band in 1978, he came back to fill the top slot once again in the GUS Band in 1982.
Trevor is married with four children.
