Watch Steve Martin’s Orchestral Performance of ‘Which of the Pickwick Triplets Did It’

Steve Martin is showing off his musical chops in a brand new performance of “Which of the Pickwick Triplets Did It?,” which was written specifically for the popular Hulu series Only Murders in the Building by songwriters Benj Pasek, Justin Paul, Marc Shaiman and Scott Wittman.

“Which of the Pickwick Triplets did it? / Who of the crew could commit this crime? / Might a little brat, make a mommy go splat? / It’s a story pretty gory for a nursery rhyme,” he sings in the dramatic chorus.

The third season of Only Murders premiered Aug. 8, with stars Selena Gomez, Martin Short and Steve Martin returning as true-crime-loving neighbors who get wrapped up in a murder mystery. Back in April, Gomez took to Instagram to tease Streep’s guest appearance by sharing a photo, smiling wide alongside the Oscar-winning icon on the series’ set.
