Mac DeMarco releases his mildly controversial new album Here Comes The Cowboy at the end of the week, and he promoted that release last week with a performance on Jimmy Fallon’s Tonight Show, where he treated viewers to a run through early single “All Of Our Yesterdays.” What we didn’t know at the time was that DeMarco also recorded a special performance backstage at 30 Rock.

Today Fallon’s people have published well-produced footage of DeMarco and his bandmates playing a lounge-ready cover of Feist’s Let It Die track “One Evening” in the backstage area. He preceded the performance with a dedication: “This is a song by the queen of Canada. Most of you Americans probably don’t realize that we have a queen, but we do. Her name is Leslie Feist. We love you, Les.” It ends with a gap-toothed grin and another profession of love.

Watch the performance below, where you can also hear Feist’s original.

Here Comes The Cowboy is out 5/10 on Mac’s Record Label.
