Jimmy Kimmel plus Brad Paisley plus … Huey Lewis and the News?

Oh yes—and it was glorious. At Entertainment Weekly’s South by Southwest party Monday nigh, the ABC late-night host and the Grammy-winning country singer took over the pop-up Samsung Studio venue in downtown Austin for a concert and party that went well past midnight.

Paisley performed a 90-minute set for SXSW partygoers, along with several celebrity attendees, includingVeep star Julia Louis Dreyfus and Green Bay Packers quarterback Aaron Rodgers. In addition to his own hits, Paisley played covers of tunes by Eric Clapton and local legend Stevie Ray Vaughan. But perhaps the show’s most memorable moment came when the singer launched into a surprise rendition of Huey’s ’80s MTV standard “I Want a New Drug” and was joined on stage by a harmonica-playing Kimmel, who was decked out in a shirt that was most definitely Western.

Kimmel, who was recently the the subject of an EW cover profile, marked his second year of relocating ABC’s Jimmy Kimmel Live! from L.A. to Austin for a week of special SXSW performances. Referencing one of the city’s legendary BBQ joints, Kimmel joked on the air: “We’re here for a whole week — because that’s how long it takes to get to the front of the line at Franklins.”
