Whenever Tracy Chapman takes the mic, you just know a pin-drop moment is coming. The Grammy winning singer was on rare pin-drop form when she appeared overnight as the musical guest on The Late Show With David Letterman for an acoustic performance of Ben E. King’s "Stand By Me." 

David Letterman Reveals Final Musical Guests

In his intro, Letterman explained there were two songs that he loved as a kid, Simon & Garfunkel’s "America", and King’s classic. A clearly grateful Letterman later thanked Chapman, “it means a great deal to me. I’m so happy you could do this for us.”

Letterman, of course, is in the final straight before he retires from his legendary late night stint after 33 years. Watch the clip below.
