Things got even weirder — but in a good way — during Weird Al Yankovic‘s Saturday night concert at New York City’s Radio City Music Hall: During his performance of “Yoda,” the eccentric singer brought out Hamilton creator Lin-Manuel Miranda to help out on the chorus.

Yankovic pointed his mic at the audience to sing along before saying, “Okay, now just Lin-Manuel!” The Broadway star and composer then rushed onstage amid applause, as shown in audience-shot footage.

That night, Miranda tweeted, “In 9th grade I sat in an upper box of the Beacon with [Alex Sarlin] & Emily Pinkowitz & we screamed ‘Yoda!!’ It was [Yankovic’s] encore.” Posting a selfie with the musical maven, he followed up, “We truly believed our screams made Yoda happen. It was, at that point, the best moment of my life. Today was a VERY close second.”

Yankovic posted another photo with Miranda backstage, but this one showed a number of other celebs were also in attendance, including Tina Fey, Saturday Night Live veteran Taran Killam, Michael Ian Black, and Weekend Update writer Alex Baze.
