Last night, the Obama Foundation closed out its inaugural Summit event in Chicago with a massive concert. The event featured appearances by The National, Gloria Estefan, Nas, Brandi Carlile, Aziz Ansari, and Francis and the Lights. Chance the Rapper headlined the show, and he surprised fans with a pair of special guests.

Chance welcomed his frequent collaborator Francis and the Lights to perform “Dear Theodosia”, their  contribution to last year’s Hamilton Mixtape. As they entered the second verse, Hamilton creator Lin-Manuel Miranda joined them on stage to sing along. Check out fan-shot footage of the all-star rendition, which includes a nod to Michael Jackson’s “Man in the Mirror”, up above.

After handling creative design and curation of the Obama Foundation Summit concert, Chance will next host Saturday Night Live on November 18th alongside musical guest Eminem. Who knows what sort of surprise that appearance is going to bring.
