Gibb was the ‘monologist’. He recited poems and monologues.

Gibb had studied elocution before enlisting in the AIF.

After his return to Sydney after the war, Gibb established an elocution school there.

Gibb enlisted again in World War II, in December 1942, and rose to the rank of captain.

Between the wars, Gibb performed often, alongside his wife, Ethel Isabel Lang.

The Anzac Coves was the first field theatre troupe of the AIF and was financed by the Australian Comforts Fund, which supported the troops serving at the front.
