Toon Rock: Hanging on The Telephone (2017)

 From 2017's "Batman & Harley Quinn":

While teaming with Batman and Nightwing, Harley (Melissa Rauch, The Big Bang Theory), as a favor to a friend, rocks out with a cover of "Hanging on The Telephone", first recorded by the Nerves in 1976, then famously covered by Blondie 3 years later.

Check out the Easter egg in the video, with a henchman trying to mock Batman with a little Batusi from the 60's.
