"The Office" actor John Krasinski has gathered the "Hamilton" cast to surprise a fan in his YouTube show, "Some Good News, yesterday, April 5.

During the latter half of the show, Krasinski opened up on the story of a 9-year-old "Hamilton" fan, Aubrey, who was unable to see the musical because of the coronavirus outbreak. His intro was accompanied by a tweet coming from the child's mom.

"But very sadly, there was one little girl whose dream could not come true because her long awaited 'Hamilton' experience was cancelled. Luckily, she toughed it out though, turning to the one person she can count on... Mary Poppins," Krasinski narrated. 

"This corona thing is a bummer, ain't it?," the SGN host asked.

John Krasinski then put the 9-year-old on video call and explained the importance of social distancing, before promising that he will get Aubrey and her mother to New York to see "Hamilton" live on Broadway. 

He then quipped that he'll never be number 1 on the child's fan list, saying that she might be a bigger fan of his wife. The child smiled, then answered "about the same."

Krasinski then revealed his first surprise, none other than his wife and "Mary Poppins" herself, Emily Blunt. When Aubrey explained that she couldn't see "Hamilton" and watched "Mary Poppins Returns" instead. Both films featured American composer Lin-Manuel Miranda.

"He's in it, I mean, he's not the best part of it... he's more like a backup dancer," Blunt quipped before Miranda himself popped right in the middle of the conversation, leaving the kid speechless.

As the couple were kidding with the Hamilton playwright, multiple log-in sounds from Zoom were heard as Miranda played the intro to "Alexander Hamilton." The cast, all from separate places, started to sing their parts in a full performance of the now-iconic Broadway song.

"If you can't go to Hamilton, we're bringing Hamilton to you," John Krasinski said.

The all-star rendition of the popular musical piece included Daveed Diggs, Phillipa Soo, Okieriete Onaodowan, Christopher Jackson, Renée Elise Goldsberry, Jasmine Cephas Jones, Javier Muñoz, and Jonathan Groff.

Aside from the "Hamilton" surprise performance, Krasinski also shared the highlights on other fan-made versions of his quarantine show - from Okanagan to Tennessee, and even to other parts of the globe. 

"And the intellectual property heist didn't stop there, no, it made its way all the way to Saigon," Krasinski joked before featuring an SGN version in Vietnam. He said that the "spin-offs" are not only "SGN-approved, but encouraged," explaining that he is aware that he is "only delivering the good news, you are the good news."

As of this writing, the Some Good News YouTube channel has 1.15 million subscribers while their official Twitter account currently has 42.4 thousand followers.
