"We Are Young" band, fun., was the musical guest on last night's episode of "Saturday Night Live," hosted by Louis CK.

The band performed its hit single, "Some Nights," the title track off fun.'s 2012 album. (Watch that clip above.)

They also played "Carry On," another single off the "Some Nights" album.

fun. tweeted a picture from the show on Saturday night.

"Some Nights," the second album from fun., was released in February of 2012. The band is a supergroup of sorts, made up of lead singer Nate Reuss (formerly of The Format), Andrew Dost (Anathallo) and Jack Antonoff (Steel Train). Antonoff has made some tabloid waves, as he's reportedly dating "Girls" creator and star Lena Dunham.

In a bit of a twist, fun. didn't perform its biggest hit, "We Are Young" on "SNL." The first single from "Some Nights" was released last year in the lead up to the band's album release, and hit number one on the Billboard Top 100.
