Kathryn Hahn recaps the MCU in a song before “Agatha All Along”

Keeping up with everything that’s happened in the MCU so far is… a lot. We’ve already done it for you, but on Wednesday night, Kathryn Hahn, star of WandaVision and Agatha All Along, gave us her own recap – in song.

Hahn returned to “Jimmy Kimmel Live!” for another night as guest host and welcomed Joe Locke as one of her guests for the show. The “Heartstopper” star plays Agatha’s confidant in her upcoming series on Disney+. But before Locke came out, Hahn did a little bit of setting the stage for the show.

“Agatha doesn’t premiere on Disney+ until September 18, but in the meantime, a lot of people have asked me if they need to watch every single Marvel movie and show to enjoy it,” Hahn explained. “And the answer is no. But if you want to stay up to date with everything happening in the MCU, I’m going to do that for you right now, through the power of song.”

Then the piano started playing and Hahn actually began a musical number that began with “Iron Man” and culminated with “Agatha All Along.” A background choir soon joined in – all wearing Avengers costumes, of course – and an enthusiastic audience clapped along.

Hahn had to correct her backup singers for “incorrectly” referring to the Avengers as “bangable” instead of “bankable.” She also made a reference to Josh Brolin’s Thanos, whose chin “looks like giant purple testicles,” but less than four minutes later she had nailed it.
