Big in Japan. It's a phenomenon well known to generations of rock bands, elevated from relative obscurity at home to apparent god-like status in the Land of the Rising Sun.
Met at the airport by screaming fans, groups struggling to get in their own charts get an unexpected -- and often career-reviving -- taste of Beatlemania, Orient-style.
This weekend, it's going international -- "Live at the Budokan" on tour, in Longchamp. Thousands of enthusiastic Japanese will invade Paris for an event that some say has become the crowning jewel in a new national obsession.
It's not pop music, but horse racing -- a sport that has emerged from a murky association with underworld gambling to become an aspirational pastime for a younger generation of Japanese racegoers and a rival to the likes of baseball and football.
"Many years ago, horse racing had a kind of bad reputation but there has been a big change in perception among Japanese citizens," Fumitaka Tsuruoka, the Paris representative for the Japan Racing Association, told CNN.
"It is true that horse racing still offers betting but it is loved by many people as a sport, which they could be enthusiastic about."
A party of some 5,000 horse-racing-mad fans is traveling to the French capital to see if their nation can finally end its hoodoo in one of the sport's premier events -- the Prix de l'Arc de Triomphe.
The passion and desire to win European racing's richest prize -- with a purse of €4 million ($5.4 million) -- is almost verging on an obsession, but it is an obsession with good reason.
Japan has come agonizingly close to winning the big prize at Longchamp on numerous occasions. The most recent attempt was Orfevre, who last year had been a frontrunner only to be upstaged by the unfancied Solemia.
One of Japan's most famous horses, Deep Impact, was backed at 1-2 to win in 2006 only to falter rather dramatically, while three years later El Condor Pasa had boasted a lead of five lengths but was beaten on the line by Montjeu.
L'Arc is effectively the jewel missing in the crown of Japanese racing, the likes of the Dubai World Cup and Melbourne Cup already conquered long ago, and it is an event that will be watched on television by some 30 million people in Japan alone, nearly a quarter of its entire population.
Tsuruoka, however, insists his nation's love of the race is "not an obsession."
"It's just it is the most famous and desirable overseas race in my country and a lot of Japanese people and the horse connections have a great ambition to win the race," he said.
"The Japanese have made a lot of efforts to catch up with European and American racehorses for more than 50 years since the first overseas challenge in 1958, and one of the goals is to win the Prix de l'Arc de Triomphe. We are almost there."
Japan, as has been the custom in recent years, can aspire to victory this year.
Last month, Orfevre won the Prix Foy at Longchamp for a second successive year and and is top of many bookmakers' odds lists for Sunday. Fellow contender Kizuna, sired by Deep Impact, triumphed over in another Group Two race, the Prix Niel on the Arc distance of one-and-a-half miles at the same venue.
For the Japanese punters, backing their own horses is a source of nationalistic pride. They betted so heavily on Deep Impact that the seven-time Japanese Grade One winner was an overwhelming favorite at the 2006 Arc.
"I heard they had bets of about €500 each on Deep Impact and, had it won, the story goes they wouldn't have even cashed it in as they wanted to keep the memento," says Ed Dunlop, who has enjoyed more success than most as a foreign trainer on Japanese soil.
The Briton is best known for Snow Fairy, which in 2010 and 2011 enjoyed back-to-back victories in the Queen Elizabeth II Commemorative Cup in Kyoto, and his family has long been interlinked with Japan -- his father John was among the first foreign trainers to be invited over.
Dunlop says the obsession with horse racing in Japan is not solely the reserve of the Arc, with passion as fervent -- in fact, even more so -- for its domestic races.
"It's enormous compared to what we're used to," he explains. "Horses have huge followings and jockeys too. You'll see posters of them out there, which you'd never see in the UK for a second.
At the Japan Cup (the biggest race on the calendar), there's 100,000 people there. The atmosphere is like nothing I've heard before. The noise is genuinely unbelievable."
It is a sentiment echoed by jockey Ryan Moore, winner of this year's English Derby on Ruler of the World, who likened it to another sport.
"It's the one time when it feels like you're inside a football stadium," he says. "There's just a crazy amount of shouting. It seems like it's like that every day on the track.
"When you get off the plane and the bus, you have people trying to get pictures, sign autographs, books and stuff like that. It's stranger when it's like half past 10 at night. Japanese jockeys are used to it as they get it a lot."
