This, the Best of the Runners-up semi-final, is being staged at the New University of Ulster in Coleraine, and by sheer coincidence includes an Englishman, an Irish-woman, a Scot and a Welshman.
Tonight's winner will fill the last place in the Final line-up. The contenders are:
Barry Jones (fitter) - British Prime Ministers
John Shepherd (air traffic controller) - Life and Works of George Borrow Beatrice Syms (art teacher) - Life and Works of Jane Austen
James Davis (teacher) - The Mountains of Scotland
