Why did aaron copland write the piece fanfare for a common man?

Copland, in his autobiography, wrote of the request: "Eugene Goossens, conductor of the Cincinnati Symphony Orchestra, had written to me at the end of August about an idea he wanted to put into action for the 1942-43 concert season. During World War I he had asked British composers for a fanfare to begin each orchestral concert. It had been so successful that he thought to repeat the procedure in World War II with American composers". A total of eighteen fanfares[1] were written at Goossens' behest, but Copland's is the only one which remains in the standard repertoire.
