What if Tom Petty’s rock classic “Free Fallin’” was exclusively about horses… and performed by Kevin Bacon in disguise? That’s what The Tonight Show Starring Jimmy Fallon imagined on Monday night, as Bacon took the stage in full Petty garb to perform the “first draft” of “Free Fallin,’” titled “Free Horses.”

The Behind the Music–esque spoof shows Bacon starting off the performance innocently enough, but then delving into more horse-obsessed lyrics as the song progresses. “She likes ponies, but not as much as horses / She likes horses, much much more / She likes unicorns, but she calls ‘em ‘horny horses’ / She loves horses, yeah that’s what she loves,” he sings.

Props to Bacon for keeping a straight face while performing…and for finally, finally delivering that chorus! Bacon currently stars in Amazon’s I Love Dick, from executive producer Jill Soloway (Transparent).
