As they wrapped up their third and final night at the Barclay's Center in Brooklyn, everyone knew Arcade Fire would start their encore off with a New York-specific cover. The first night (Aug. 22), they were joined on-stage by Buster Poindexter for a funky rendition of 'Hot Hot Hot,' and the following night (Aug. 23) Marky Ramone sat behind the drum kit to cover two Ramones classic.

Last night (Aug. 24), the founding member of the Talking Heads, the one and only David Byrne, provided some assistance as Arcade Fire covered Suicide's 'Dream Baby Dream.'

It might not be a huge shock that Byrne would be the night's special guest -- after all, on Saturday, the "fake" band (complete with bobbleheads) that opened the encore pretended to sing the Talking Heads' 'Psycho Killer.' Perhaps it was a coincidence, perhaps it was Arcade Fire giving some clever foreshadow. Regardless, Byrne -- complete with a Dracula-esque costume -- belted out some hauntingly beautiful vocals for the cover. Check out his performance in the fan-filmed footage above.

This isn't the first time Byrne has collaborated with Arcade Fire -- on or off the stage. On a deluxe version of the band's third full-length LP, 'The Suburbs,' Byrne is featured on the track 'Speaking in Tongues.'

And a few years before that at a gig at New York's Irving Plaza, he joined Arcade Fire on-stage for a Talking Heads cover:

Arcade Fire kick off their two-night stint in Chicago tomorrow (Aug. 26) followed by gigs in Toronto and Montreal. Visit their official website here for details on the remaining dates of their 'Reflektor' tour.
