Concertgoers who attended Alicia Keys’ “Freedom” tour stop at Madison Square Garden in New York City on St. Patrick’s Day were in luck. The Grammy winner thrilled her hometown crowd by bringing out Mr. and Mrs. Carter.

Alicia and Beyoncé united to perform their collaboration “Put It in a Love Song” live for the first time together, and she capped off the evening by singing her city’s anthem “Empire State of Mind” with Jay-Z. Even Alicia’s man, Swizz Beatz, briefly took the stage for “On to the Next One.”
