For many fans, the Lions’ first Australian tour in 12 years is the catalyst to sight-see and reunite with relatives.

Joining Watkins at the MCG will be his uncle Kevin Adams, cousin Kevin Lloyd and godson Morgan Lloyd, 15, who are visiting from Wales.

It will be the first holiday since Christmas for Watkins, who, as a publican, works seven days a week.

The quartet will reserve extra cheers for the Lions’ only Welsh player, Jac Morgan.

They won’t need much persuasion to gather with fellow spectators and sing the Welsh national anthem, Hen Wlad Fy Nhadau (Land of My Fathers).

“Crowd singing is part of our Welsh heritage,” said Watkins, who pointed to a YouTube clip of a stirring mass rendition of the anthem before a 2013 Wales versus England match in Cardiff.

Saturday’s MCG match against the Wallabies and this Tuesday’s game against a First Nations and Pasifika team at Marvel Stadium are the Lions’ first matches in Melbourne since 2013. Lions matches during this tour are being aired live on Channel 9 (Nine is the owner of this masthead).

The Lions team, which was first formed in 1888, includes top players from England, Ireland, Scotland and Wales.

In 2001, its name was changed from the British Lions to the British and Irish Lions. It “doesn’t roll off the tongue” says Irish-born fan Dave Dillon, but he says the team is usually just called “Lions”.

Dillon, from Wellington in New Zealand, will go to the MCG match with three of his brothers — Barry, from Kildare in Ireland, and Liam and Neil, now of Cape Cod, in the US.

“The games are great, but I’m looking forward to going for a pint with my brothers, and hanging out,” Dave said.

Dillon says there’s nothing like watching the best players, in an electric atmosphere at a big match.

“The craic and the banter is brilliant,” he said.

“Everybody’s having a laugh, you’re singing songs, you’re making fun of each other,” Dillon says. “It’s always good-humoured.”

Rebecca Grice, a Lions fan visiting from Lincolnshire, England, is going to the MCG test with her friend Georgia King, a Wallabies supporter from Sydney.

They’ve been close since being pen pals as 11 years olds, 20 years ago.

Grice, who played rugby union for nine years, and who supports Leicester Tigers, recently converted King, and King’s four-year-old son, to the sport.

“Her enthusiasm is very contagious,” King said. “Rebecca knows every player. She can answer every question.”

Grice is a big fan of Lions player Ollie Chessum, who is from Lincolnshire, like her.

On July 5, Grice, King and King’s nan, Jill Wilkinson, watched the NSW Waratahs rugby union team play the Lions at Sydney’s Allianz Stadium.

“The atmosphere was so great. I loved it,” said King.

Earlier that day, in Sydney’s George Street, Grice spotted Chessum and four other Lions players, and rushed up to take a selfie with them. “It was very exciting,” Grice says.

“But I was so nervous and all I could think to say to them was: ‘Are you having a good day off?’ And they were playing that night! I’m mortified by that!

“One day I hope I’ll meet them again and actually have a conversation with them.”

While Grice has travelled to Paris, Wales, Ireland and Twickenham in England to watch England play, she will watch her first live Lions match at the MCG.

King and Grice along with King’s husband and father-in-law will drive to Melbourne from Sydney, and stay with King’s relatives.

On Saturday, they will get to the MCG early to “soak in the atmosphere”, Grice said. “I’m so excited.”

Lions games are held every four years in different countries.

“And that’s what makes this so special. It’s an occasion that brings everyone together, to experience something that you might never get to experience again.”

King says Grice has been raving about the event for years.

“It’s amazing to think that now it’s here,” Grice says.
