It is commonly stated that Ó Dálaigh and Cusack picketed the Dublin launch of Disney's Darby O'Gill and the Little People, for what they felt was the film's stereotyping of Irish people.
Whereas up to 1973, those ceremonies were exclusively denominational, the ceremonies for the inaugurations of President Childers in 1973, President Ó Dálaigh in 1974 and President Hillery in 1976, were multidenominational, with representatives of the Roman Catholic, Church of Ireland, Presbyterian, Methodist and the Jewish faith taking part in the ceremony.
