It has a very predictable result but the Royal Black Preceptory's Sham Fight at Scarva continues to attract up to 100,000 every year, mostly families having a fun day out.
And among the 4,000 members of the Royal Black Institution on parade today are John Adair and Brian Johnston, both members of the local RBP 1000 - and both home-bred superstars for the day.
The pair take a jovial approach to their re-enactment of the Battle of the Boyne, as the troops of King Billy - played by John - trounce those of King James, played by Brian, at the scenic Scarva House demesne.
While Brian's a newcomer to his role, John has made a handsome King Billy for two decades, and has no plans to retire just yet. A part-time sheep farmer, he lives in Clare, near Tandragee, with his wife Elizabeth, who helps him organise the trade stands and stalls at the colourful event.
'We've never made it political, that's why we get 100,000 every year'
I didn't need sword-fighting lessons to play King William - it all came naturally! They're real swords but fairly lightweight. I always win the fight, but I try not to be too hard on King James. There's been nobody hurt so far - they're always able to walk away in one piece.
We got our wigs made specially in 1990 - I still have my own hair under my one. I do feel I'm getting too old for this sort of carry-on, but I'll still do it another while. I was a foot soldier at the fight when I was younger. I got promoted to King William in 1995 and it's got bigger and bigger every year.
We've never had provocative flags flying, like those on that Carrickfergus bonfire, and there's never any tension. It really is a family day out and anybody can come. We've had councillors from Louth and Ballyjamesduff and they really enjoyed it. We've never made it political. I think that's why we can get between 80,000 and 100,000 coming every year.
We don't ban alcohol and we can't stop anyone from taking it in, but we've never had any problems with drunkenness. There's up to 30 of us in the RBP involved in organising the day, so it's very well-run.
It's an early start for me. I get down to the field for about 5.30am or 6am to check everything's in place. We're having RBP and Ulster Scots display marquees for the first time this year, plus Ulster Scots groups are performing from 9.45am-11.30am. We've also got a big screen in the village so everybody can see the action. People get up early and line their deckchairs along the route to watch the parade.
I've met people who have flown in from abroad for one reason only, to see the Sham Fight. And I've run into others afterwards who have been very disappointed to miss it. Most of them know a bit about the history and culture.
The day is great for local business and hotels, and it's good fun for us taking part, with all the pageantry. I've got soaked many a time but haven't been struck by lightning yet. We have had one or two badly behaved horses over the years and the odd problem with flags dropping off, but no major mishaps.
We'd like to take the event to an even more professional level in the next few years, with the help of the tourist board. I'd like to see world leaders invited - Bill and Hillary Clinton would be great as guests. I'll have to get a number for the White House.
I don't do any other acting, though. I don't think I'd make it in Hollywood! It's a tiring enough day - you're ready for your bed when you get home."
Brian Johnston (50) took over as King James for the Sham Fight last year. An experienced horseman, he works at Scarvagh House Stud and lives in Scarva with his partner Hylda Mills, daughter of the late Alfred Buller of Scarvagh House. Brian says:
I was the assistant for years to the old King James, Colin Cairns, so I knew all the moves off by heart when I was promoted last year. We've done the fight in all weathers - there was one year the rain fell so hard, the water was running out of us and the green dye from my coat seeped into my skin. I had to give myself a good scrub to get it out.
We're kind of treated like stars on the day. Everybody knows us and we have to pose for plenty of photos. There have been a few who get a bit carried away with the sight of the green uniform and you get a bit of stick, but there's never any bother. It's a totally different day out to the Twelfth - it's very laid-back and everybody from the wider community is welcome.
There's no tension or hostility, and kids - as long as they know where the car's parked - can run off and do what they like, without coming to any harm. It's a very well run event and there are plenty of stewards on hand.
We've been getting more tourists over the years - Chinese, Americans, from all over. We all really enjoy the day; it's good craic. Of course, I never win the fight, but I don't get hurt, even though we use real swords.
I've had no real disasters over the years, but if there's a cranky horse, I'll get him. I'm used to working with thoroughbreds at the stud, but we couldn't use them in the field. We hire four ordinary ones for the day for about £300, from Lime Park Riding School, in Magheralin.
They're only used for half an hour but by the time you lift them and leave them back, it takes the whole day. We take them down for a hack to let them see the whole thing before it starts.
It's a bit of a family affair for us. Scarvagh House is my partner Hylda's home place and I've worked for her brother for years. It's great to see the crowds getting bigger every year as well as having the backing of the Tourist Board. And everybody's welcome, no matter who they are or where they're from."
