Last night (February 15), Panic! at the Disco covered Sisqó’s 2000 hit single “The Thong Song” with a little help from Sisqó himself.

The newly minted supergroup Panic! at the Sisqó made their debut appearance on Jimmy Kimmel Live! for Mash-up Monday. Lead singer Brendon Urie got to show off his rap chops as he made his way through the song’s fast-paced verses, while Sisqó jumped out at the chorus to help with some of the high notes.

With its mid-chorus key change, “The Thong Song” is not exactly the easiest tune to sing live, but both Urie and Sisqó had the pipes to handle it. Watch their performance below.
