The Black Keys' promo blitz in support of their just-released eighth album 'Turn Blue' continued last night, when the duo stopped by 'The Colbert Report' for a chat and performance.

And like their recent stops on 'Saturday Night Live' and 'Late Show With David Letterman,' the Keys pulled out 'Turn Blue''s first single, 'Fever,' as their main number. You can watch that one above.

They also played an online exclusive version of the album's title track, which you can watch below.

In addition to the performances, the pair chatted with host Stephen Colbert, touching on everything from the band's newfound love of winding guitar solos and the Grateful Dead to drummer Patrick Carney's physique and Colbert's colonoscopy.

The interview precedes the performance of 'Fever' in the above video.
