On Sunday, the Broadway community will celebrate Cordero's life in an exclusive memorial tribute that fans can partake in. Theater-focused streaming platform Broadway On Demand will air the free ceremony at 7 p.m. ET.
Kloots encouraged her husband's fans to participate in the public memorial.
"There has been so much love going into making this memorial as special as Nick was. Thank you to any and all who gave their time and talent so graciously," she wrote.
Cordero's former castmates in A Bronx Tale, Bullets Over Broadway, The Toxic Avenger, Rock of Ages and Waitress are slated to make special performances. The event will also feature photos, videos and commentary from those he grew up with and worked with.
