Disney's animated classic Beauty and the Beast celebrates its 25th Anniversary this year, and last night, the studio brought this timeless classic to Alice Tully Hall in New York City for an anniversary screening. Fans were in for quite the surprise when Angela Lansbury, who voiced Mrs. Potts in the movie, took to the stage, alongside Alan Menken to sing the iconic theme song. As you can see in the video below, Angela Lansbury can still belt out a tune at 90 years old.

The video, which comes courtesy of ABC News, shows the iconic actress even delivering a line from the film towards the end of her song, which was met with laughter and applause from the New York crowd. For fans who weren't able to attend this screening, Disney will release the 25th Anniversary edition of Beauty and the Beast on Blu-ray September 20.
