First it was toilet rolls, hand sanitiser and pasta, but now Covid-19 has caused a new and unexpected shortage in Northern Ireland: clowns. David Duffy, co-owner of Duffy’s Circus, is appealing for locals to put on the traditional red nose and to learn the skills of a clown. With circuses closed for more than 500 days, many performers left Northern Ireland for other places which reopened their big tops more quickly. So what qualities does Mr Duffy say are needed to have them rolling in the aisles? Vulnerability, adaptability and the capacity to think on your feet – even while wearing enormous shoes.
