He's the man behind America's most popular blockbuster musical, "Hamilton." Snagging both a Tony and pulitzer prize then conquering the big screen. ??? Away away ???

And lin-manuel Miranda, well, he is here with us right now. Come on out. ??? Mwah. Welcome. Welcome, welcome, man. Thank you for having me. You are one busy fella and -- Trying to keep up with you, Strahan. No, you are much busier and more talented than I many. In two weeks you were able to write this song and call all the superstars and make this collaboration happen. You got them on board and recorded and you released it. How were you able to do that, so quickly. Well, you know, unfortunately, one of the things any Puerto rican who has ties to the island had in the immediate wake of the hurricane was time because there was this terrible silence while we all waited to hear from our families and my social media, my Facebook, my Twitter was filled with my friends and family, has anyone heard from San Juan, and that's how I had the idea for the song. I said if we can get all 78 towns in the lyric for the song their names will never be forgotten again. That was the impetus behind writing the song and then you burn up your rolodex and you tweet the people whose numbers you don't know and really every artist made miracles happen. I'll tell you one story. You know, I wrote to this rapper who I'm a fan of from Puerto Rico, didn't hear from him and all right, I'm sure he's very busy, Saturday like this past Saturday I get an e-mail from him, I just got power back. I just got your e-mail. I'd love to be a part of it. I write can you get to a studio. He says, yes, there is a studio in San Juan, I can record the verse. The next day I get an e-mail, I don't have enough bandwidth to send you a waif file. I'm with him while Gloria estefan is recording and Gloria estefan says I'm flying to Puerto Rico for relief efforts tomorrow. I go, can I get you a memory stick? And Gloria estefan flies to Puerto Rico, that was well documented with Bernie Williams and then, you know, we don't know if it will happen and that night I get an e-mail and a picture of them holding a memory stick. I love that. On the track. To a person it was like that. Everyone just sort of moving mountains to make this happen in record time. Because it is so important. I want to talk about the choice of the song, "MARIA" from "West side story." This is the worst storm Puerto Rico has ever experienced in its modern history and knew that name would forever have a different connotation on the island and yet I have a musical theater brain. That's where my head goes when I hear the name MARIA so I thought is there anything I can flip. Hip-hop we flip a sample and we change the meaning and the goal with this was to flip the meaning of this song to be about -- to be about Puerto Rico and the title "Almost like praying" because thoughts and prayers are great but thoughts and prayers are not enough. We need more. We need action. We need the government to respond to be equal to the response of the people which, you know, I have never had more hope in the American people and people all over the world. I go to my Twitter feed people breaking their piggy banks and employers matching employee donations. We are not the issue. If our government can step up to where the people are, we'll be on the road to recovery a lot Nasr. Talking about your Twitter feed, that's for sure. You're full of hope right now. You were full of anger this weekend as well. Do you think things are changing now? Is the government stepping up? I don't know. You know, the tweets I wrote this weekend made news because normally my Twitter feed is full of dad jokes and dog videos and pictures of my son playing with trains and yet I've never seen a sitting president attack the victims of a natural disaster before. That is without precedent and that is why my words were without precedent. So, you know, I didn't see the press conference in Puerto Rico. I was busy mixing and mastering the song. I waited to hear are we increasing aid? Are we increasing troops? Short of that I don't need another photo-op but people to help my island. You said your island. You're from Puerto Rico and your father Luis is with you today. How is your family. They are doing the same as everybody he on the island. They're putting on a brave face for us and yet I know my cousin Kevin waited 12 hours in line for gasoline and they were only giving out $20 worth of gasoline which is just enough to get back home. It's dire. We're still in a humanitarian crisis and we need all the help we can get. I tell you what, we know you have a lot of work to do and know you have to run. We are so happy you came and talked to us about it. Thank you for making a difference.
