A trio of Broadway Carolers will be on hand to carol in and out this special ceremony: The Madison Avenue B.I.D. has announced that Cassie Donegan, Miss America 2026, will “flip the switch” illuminating the shimmering holiday lights decorating over 100 street trees located on Madison Avenue between East 57th and East 86th Streets. Open to the public, on Tuesday, November 18 at 5 pm, the former Miss New York, crowned on September 7th as Miss America 2026,  will appear on the Miracle on Madison Avenue stage at  Madison Avenue and East 63rd to enchant the crowd with a surprise Holiday song - surrounded by MSK officials, the beloved MSK Caring Canine therapy dogs, and the Madison Avenue holiday carolers.
