Sturgill Simpson has the No. 1 country album this week, and the Kentucky native stopped by Late Night and found a duet partner in host, Stephen Colbert.

Simpson sang his new single, but not before the unlikely new duo sang their love for Waffle House, and the proper way to act when visiting one.

Hey, you better behave when you go to eat at Waffle House! Simpson also sang "Brace Yourself (Live a Little)," off his brand new album, A Sailors Guide to Earth. We've got that for you down there.
