The eight-year-old was ridden by jockey Arthur Freeman and trained by Tom Taaffe Sr., and became the fifth Irish winner of the Grand National since the Second World War.
Mr What's trainer Tom Taffe left it until five days before the race to engage Arthur Freeman, as he had wanted his son Tosse to partner his entry.
However Tosse was expected to ride the highly fancied Sam Brownthorn and with options for a replacement running out, Taffe booked Freeman, who himself had been left without a mount after losing the ride on Athenian to Derrick Ancil, having two other engagements withdrawn, and losing his standby slot on Never Say When as the injured Stan Mellor was passed fit a week before the race.
Derrick Ancil reported that his mount, Athenian's race ended at the nineteenth fence, stuck with "Forelegs on one side and hind legs on the other."
Mrs Topham was forced to defend the race after a combination of poor weather and moving from a Friday to a Saturday led to a notciably reduced attendance in the enclosures and out in the extremes of the course.
