The British retro-soul auteur Mark Ronson just scored his first ever #1 single in his native UK thanks to “Uptown Funk,” the ridiculously fun Morris Day pastiche that he made with Bruno Mars. (It’s #5 over here, too.) Last night, Ronson and Mars and the music video’s supporting cast showed up to perform on the insanely popular singing-competition show The Voice. Unlike in their SNL performance, Mars and Ronson didn’t just slavishly recreate the song’s video this time around. Instead, they went for a full retro Soul Train effect, with giant flashing lit-up letters and an actual limo onstage. Also, Mars sang the whole song in curlers, which is just an awesomely absurd touch. The whole “Uptown Funk” phenomenon remains a ton of fun, and you can watch the performance below.

Ronson’s album Uptown Special is out 1/13 on RCA. Weirdly, the novelist Michael Chabon wrote most of the lyrics.
