A Northern Irish town becomes an unlikely centre of 1969’s sporting craze. Should you put your money on Muhammad 'Mustang' Ali or Tully Tornado? Or will the Mad Barber overcome his bad luck and beat the favorites? Join Gordon Burns in Crumlin to meet the rats, check the form and watch the race. See if you can spot the gerbils amongst the rats or perhaps you’ll see a familiar face in the crowd. Then join Leslie Dawes in Bangor as the local hopefuls prepare for the world championships.
