Cast your mind back to the summer when 1,000 Foo Fighters fans recorded a version of Learn To Fly in a bid to get the band to play in their local area.
The video went viral, the band saw it and agreed to perform in Cesena, Italy.
Last night that gig happened and Dave Grohl told the crowd how touched he was by the effort they'd made with the video.
"To see you people, singing our song for the whole world, it's the greatest moment of my life," he said.
"Of course we couldn't say no, we had to come. You trapped us, we had to come here."

The video of the fans performing the Foo Fighters track has now had more than 26 million views.
The man who organised the whole event, Fabio Zaffagnini, said that he'd he spent a year putting Rockin' 1000 together.
He said: "Italy is a country where dreams can't easily come true but it's a land of passion and creativity.
"So what we did is just a huge, huge miracle. I've been working on this project for one year, waking up every morning thinking about how to make it real."

During the gig, Grohl invited the organisers of the viral video onstage.
One lucky fan played drums for Foo Fighters when they covered Under Pressure by Queen.
The singer then invited the crowd to make a similar plea to other bands.
"I hope you do the same thing for U2, Pearl Jam, Soundgarden, Rage Against the Machine, do it for all rock bands," he added.
