Searching for the pre-show Conan Clip of him earnestly performing Radiohead's 'Creep,' no bit just an earnest performance

It appeared [I think] on an unofficial account around 2015 and has seemingly disappeared. Any chance anyone has a way to share it with me?

Edit: The clip I remember happened on the TBS television set, it wasn't a moment from the tour documentary. Conan walking around his show's set with a guitar, it was like a pre-show warmup maybe? I don't know if an audience member taped it or if it was officially released for a moment, but I know at one point a mostly full song performance was done
