Lady Gaga’s first performance ever on “Late Show with David Letterman” was quite a spectacle.

On Wednesday, Gaga walked onto the stage at the Ed Sullivan Theater, and invited Letterman, Bill Murray, and the entire “Late Show” audience across the street to the legendary club Roseland.

It was a wild scene.

Eventually, everyone made it into Roseland, where Gaga performed “Dope” and “GUY.”
