The wedding party is gathering outside Ballyclare town hall when suddenly the DUP election team is spotted. For a moment, political priorities overtake the imminent nuptials.
"It would really make the bride and groom's day if you would pose for a photograph with them," a relative tells the Rev Ian Paisley and the Rev William McCrea.
The DUP leader and the Westminster by-election candidate join Joanne Beattie and Frederick Downing for a picture that will have pride of place in their wedding album.
It's all part of a day's canvassing in South Antrim. The DUP inspires passion among its supporters. In fact, it's seen more as a family than a political party.
"I remember playing musical chairs with you when I was a girl," an old woman in a charity clothes shop tells Dr Paisley. Her friends line up to shake his hand. "This is wee Willie McCrea," says the DUP leader.
"I hope you will sort things out for us," the woman tells the candidate. "The province is falling to pieces."
"It would make you weep," says Mr McCrea, shaking his head.
The DUP election campaign slogan is "Your chance to put things right". It's aimed at those unionists who voted for the Belfast Agreement but now regret it. "They've seen IRA prisoners released, the RUC destroyed, Martin McGuinness in government and still no guns handed over," says Mr McCrea.
It's three years since the DUP man lost his Mid-Ulster seat to Mr McGuinness and next week's by-election offers him perhaps his only chance of returning to Westminster.
A Free Presbyterian minister and gospel singer who has survived several IRA murder attempts, he is a party favourite and the DUP is doing everything possible to ensure his re-election.
A huge team of canvassers is out in force on a soft, sunny morning. Paul Girvan is on the campaign trail despite breaking his leg the previous week. He hobbles around without crutches. "I've left them in the car. They don't look good with voters."
It typifies the DUP attitude. "Could you picture an Ulster Unionist doing that? They're a wimpy, weedy lot," another canvasser says with contempt.
The DUP team seems to be on first-name terms with all sorts of people in Ballyclare. A woman with a nose-ring and a respectable matron in a print frock promise their support with equal resolution.
"I'll be praying for you William," a shopper says. "That means more to me than anything," the candidate replies. He gives an election leaflet to a crowd of women in a home bakery. "You can throw darts at it if you want," he jokes. "It will take pride of place on my mantelpiece," a woman tells him.
Mr McCrea stops to pat an Alsatian called Roxy and chat to her owner. He talks about his Labrador, Sasha, which pined so much for the family when they went on holiday, it suffered a heart attack. "But she's well on the road to recovery now," he says.
Next, the DUP team is off to Burnside, a village which shares the same name as the UUP candidate. A fun-fair is taking place and Mr McCrea throws himself into the action. He hops into a miniature steam train.
"Some boys never grow up," says a party sympathiser. "Is that the Dublin train, Willie?" somebody else asks.
Then, Mr McCrea is off to the fields where he strikes up a rapport with a pony called Amber. "She's lovely," he says, patting the animal.
