NEW YORK, NY - SEPTEMBER 29: Dave Grohl of the Foo Fighters performs onstage at the Global Citizen Festival In Central Park T

In their last performance for the foreseeable future, Foo Fighters took the stage at Central Park's Great Lawn on Saturday for the Global Citizen Festival. Sharing headlining duties with the Black Keys and Neil Young with Crazy Horse, Dave Grohl & Co. performed the free show to raise awareness of global poverty and drew a super humungous crowd. (No, really. It was like, three football fields of people. Estimates put the gathering at 60,000 strong.) 

The festival streamed online and was broadcast live on Fuse. (Check out our killer live pics!) K'naan and Band Of Horses served as openers. Plus there was a surprise appearance by John Legend, who showed up to play a single song on piano: "Imagine."

But the night belonged to the Foo Fighters, who were the second headliner to perform. Let us get the bad news out of the way first: They re-iterated earlier statements that they might not be playing together again for a while. Back in August, the band told fans at England's Reading Festival that that performance was the Foo Fighter's "last show for a long time." 

Rumors immediately spread that the band was going on hiatus. Or even breaking up. Grohl quickly responded by tweeting: "Jeesh! Relax.... I was only talking TO England!! ABOUT England...Stop eavesdropping internets!" Plus, the band's management pointed out that they still had several shows lined up in America. Well, Saturday's performance at the Global Citizen Festival was the last of those shows.

Grohl made the situation clear from the Central Park stage. "Without making a big deal out of it, we don't have any shows after this," he told the crowd. "This is it man. This is the show where we come out and we play as many songs as we can in a short period of time, because honestly I don't know when we're going to do it again."

And with that, the band spent about an hour nailing all the crowd faves including "Times Like These," "Hero" and their closer, "Everlong." 

As Grohl told the crowd, "I wish we could play all night. But I'd rather see Neil Young." Still haven't had enough Foos? Check out photos from their epic set, or watch his speech—and "Learn to Fly"—below, and below that read about Neil Young's epic set, plus more on Band of Horses and the Black Keys. 

Meanwhile, the rest of the evening was no less memorable. Fact: It's impossible to be disappointed at a Black Keys concert. From "Gold on the Ceiling" to "Lonely Boy," Dan Auerbach and Patrick Carney's inimitable brand of meat-and-potatoes rock and roll translates flawlessly from your headphones to any live atmosphere, and the dudes always know how to get a crowd amped. Pro tip: See the Black Keys live. If you already have, do it again.

When Neil Young took the stage at the end of the evening, it was as if someone told him that the longer he performed his songs, the more poverty would be eradicated. (We don't think it works like that, but he really tried his darndest.) Did you know Young's Psychedelic Pill track "Walk Like A Giant" is 16-minutes long? It is, we promise. 

Then in true rock icon fashion, Young ended his set by pulling a the classic finale move, bringing K'naan, Band of Horse, the Black Keys and Foo Fighters back out on stage for a communal rendition of "Rockin' in the Free World."
