The first fan started queuing before 8am.
Heaton Park, just north of Manchester City centre, is tonight hosting 80,000 fans who've come to see the Gallaghers' homecoming.
"I would honestly say it's a real cultural moment of the 21st century," says Sam, who's from Manchester and has come here with a group of friends - including one who has travelled from Australia for the gig.
This will be the fourth time Sam has seen Oasis play, although obviously not for many years, and he says he can't wait for the moment the band comes on to the stage.
"The reaction from the fans, that's going to be really special," he says. "This band means so much to the North West."
Like many people attending tonight's concert, Sam is wearing a bucket hat.
Liam Gallagher's iconic headgear has become a part of the band's cultural legacy and they are certainly on display here, with street vendors popping up all around the park's perimeter.
Another fan, Dean, tells me he feels incredibly lucky to have got a ticket at all.
"I had seven devices out when the tickets were released and I didn't get one," he says. "And then about three days ago, a friend of mine messaged to say she couldn't make it.
"So I made it. £120 with coach travel there and back - perfect."
Dom is another fan who has come from Australia for the gig.
"We're frothing to be here, like so stoked," he says, "The atmosphere is going to be electric."

One young couple are here on their honeymoon. From Italy, they met at a Liam Gallagher concert several years ago.
"It's where we fell in love," Claudia says. "And we got married last month so we wanted to be here to celebrate."
Amanda, from Manchester, is also here with a loved one - well, sort of.
She's wearing a paper cut-out mask of her 30-year-old son Harry's face.
"He's in Melbourne and got a ticket but then couldn't come," Amanda explains.
"And so Harry doesn't feel left out," she says pulling the mask down over her face, "we've brought him with us!"
