Last night (Aug. 23) in Brooklyn, Arcade Fire fans knew they'd be treated to a cover song at the start of the band's encore -- but they had no idea the sort of surprise they were in for. Playing their second show (of three) at Brooklyn's Barclays Center, Arcade Fire invited Marky Ramone out to the stage to help them with not one, but two Ramones covers.

The rockers tore into a rambunctious rendition of 'I Don't Wanna Go Down to the Basement' followed by the always singable, 'I Wanna Be Sedated.' Ramone was born in Brooklyn, so these two covers acted as a sort of homage to him; the crowd did everything they could to honor the punk rock icon with their enthusiastic support. 'I Don't Wanna Go Down to the Basement' kicks in around the 3:30 mark in the video above leading into 'I Wanna Be Sedated' at about 5:02.

For those who haven't been following along, Arcade Fire tend to start their encores off with cover songs that pay tribute to a local celebrity in the city they're performing, e.g. covering Fugazi's 'Waiting Room' at their recent gig in Washington, D.C. At their New York Show on Friday night (Aug. 21), they commemorated the encore to Buster Poindexter and his classic track, 'Hot Hot Hot.'

As you'll see in the above video, Arcade Fire tried to trick the audience into thinking they'd be covering Talking Heads' 'Psycho Killer' (which would have been awesome). It didn't take long for the real band to walk on-stage, invite Ramone to sit behind the kit and rip into an encore no concertgoer will forget.

We think it's safe to say Arcade Fire frontman Win Butler won't soon forget it either. Near the finale of the show, he told the crowd, "Thanks to Marky Ramone. That was a dream come true."
