http://www.huffingtonpost.com/2015/05/05/ellen-albertini-dow-dead-dies_n_7213262.html Ellen Albertini Dow, who was best known for her amazing cover of The Sugarhill Gang's "Rapper's Delight" in Adam Sandler's "The Wedding Singer," died on Monday at the age of 101. Dow's longtime agent Juliet Green confirmed Dow's death to Deadline. Dow didn't start her onscreen career until she was in her 70s, but has been seen in a handful of memorable film and TV roles. Beyond her hilarious dancing grandma in "Wedding Singer," Dow also played Peterman's mother in an episode of "Seinfeld, a Choir Nun in "Sister Act," the foul-mouthed grandma in "Wedding Crashers" and a granny in "Hannah Montana," just to name a few. She also made appearances in "The Wonder Years," "Golden Girls" and "ER." Not the one from the grossest Sybian ride in history.
