Following the taping of the three-song set — performed before an exclusive crowd of about 100 people responding to blasts on Twitter and Facebook — Jay-Z spoke to a local news station about the scenario.

“It was amazing,” Jigga told MyFoxNY as he greeted fans who heard about the performance and lined up to catch a glimpse of him outside of the theater.

Though the crowd was relatively low-key, there was one high-profile guest: Diddy, who showed up to lend his support to the pair.

“I’m just here as a fan,” he said. “[The performance] was great. It was incredible. A lot of fun. You know, Hov, Eminem, New York, rooftop, summer time — it don’t get no better, baby.”

According to reports, Jay and Eminem played a total of three songs. They opened with Eminem’s latest single “Not Afraid” before moving into Jay’s “On to the Next One” (from his smash 2009 album The Blueprint 3). As a grand finale, the two teamed up on “Renegade,” the classic banger from Jigga’s 2001 album The Blueprint that represented the pair’s first collaboration.

The two MCs will be taking over this Friday’s episode of “The Late Show With David Letterman” in order to promote their upcoming concerts in each of their respective hometowns. Jay-Z and Eminem will play Detroit’s Comerica Park on September 2 and at Yankee Stadium in the Bronx on September 13. In addition to the musical performances, the two will also get involved in some comedy: Eminem will reportedly deliver Friday night’s Top 10 list, which will be “Top 10 Eminem Pieces of Advice for the Kids.”
