"I am so thrilled we can do this," Mendez told Playbill.com, "and I really hope we will sell some tickets!! They are only $25 for a great night of music, and you are doing something great for people who really need it!" 

At the 8 PM concert, the duo will be joined by Pete Donovan on bass and Mark Ferber on drums.

Audiences can expect to hear Mendez and Paguia's covers of "Ordinary People" by John Legend, "Us" by Regina Spektor, "Money" by Pink Floyd, "All My Days" by Alexi Murdoch and "Eleanor Rigby" by the Beatles, among others. 

Mendez, who was last seen on Broadway in the revival of Godspell at Circle in the Square, was also seen in Everyday Rapture, Grease, Off-Broadway's The Marvelous Wonderettes and the Ryan Scott Oliver song cycle 35mm. 

Paguia, who is the music director of the Tony-nominated Best Play Peter and the Starcatcher, composed the Fringe First Award-winning How to Act Around Cops (New York and Edinburgh Fringe Festivals). He has musically directed Everyday Rapture and Peter and the Starcatcher at New York Theatre Workshop, as well as the national tours of Disney's On The Record and Flower Drum Song.
