The Beatles on Ed Sullivan. Nirvana on Saturday Night Live. Warren Zevon on David Letterman. Sometimes, late-night TV musical performances live on forever.

Most don’t. But we still want to talk about them.

Each week on “Tonight’s Musical Guest, Today”, long-time friends Alex Beaton and Jon Hillman dive in on the music and cultural memory of a band through the arc of their late-night TV performances. Watch along with Alex and Jon as they examine and react to these musical history moments preserved in the amber of time alongside two celebrity guests and a talk show host. 

From Conan to Colbert, Letterman to Leno, or SNL to MadTV, there is no shortage of iconic late-night musical moments. And no end to the ones you don’t remember.
