Colbert replied, “Yeah I’m here Jimmy, I’m just trying on a new bandana. Tell you what, let’s change frequencies, the writers listen to this one.”

He then added, “Hey man. Do you wanna do that thing?”

The pair belted out their very own rendition of the ’80s track “NeverEnding Story”, which has a huge moment in “Stranger Things” season 3.
