Every now and then, some piece of music turns up in a (horror movie, usually) that makes me do a double take, or if I’m imbibing, a spit take.

How did (whoever the music supervisor/the star/the director) they pull that song out of the air for this movie at this moment?

Whoever supervised the pop hit clearances for “Night Swim” stumbled across (no WAY they would have remembered it) this tune by a fellow who not only once attempted a mustache, he infamously crooned about a dead skunk in the middle of you-know-where.

I know it because I worked in folk-music friendly public radio for a few years. And I interviewed LWIII a few times. Many times. He’s an actor, too. Crooned in “The Aviator” as a big band singer, plucked and played through rehab with Sandra Bullock in “28 Days.” I caught up with him on the set of that picture.

This song is a happy little ditty from the son of a magazine columnist, a fellow who used to be married to folkie Kate McGarrigle, with whom he fathered Rufus. Perfect ironic tune for a killer swimming pool picture, I think Loudon W. would agree.
