Last night, The Tonight Show had a rather unlikely musical guest: The debonair and dark-hearted self-made singer-songwriter Father John Misty, who should probably never appear anywhere that well-lit. In his FJM alter-ego, J. Tillman cranked out a rollicking version of “I’m Writing A Novel,” one of the many highlights from his Fear Fun album. Given the decor on Leno’s set, the whole thing seemed beamed in from some seedy ’70s alternate reality. Watch it below.

Fear Fun is out now on Sub Pop.
