The 9/11 Memorial & Museum, in partnership with “Choir! Choir! Choir!”, presents a special community event to mark the 9/11 Memorial Glade dedication and pay tribute to those who are sick or have died because of 9/11 illnesses and all those who responded when our nation needed it most. The program features special guest Rufus Wainwright, singing Leonard Cohen’s iconic song, “Hallelujah.”
