Dick Van Dyke's Impromptu Mary Poppins Performance Is Supercalifragilisticexpialidocious

Calling all Disney fans: Dick Van Dyke's latest appearance will flood your heart with emotions. While visiting Walt Disney's birthplace in Chicago recently, the actor, who is known for his role as Bert in Mary Poppins, gave an impromptu performance of the film's iconic number "Let's Go Fly a Kite," and it was even more magical than you could have imagined. Not only did he sing the tune with his wife, Arlene, and his a cappella singing group, The Vantastix, but the crowd even joined in for the chorus. Of course, this isn't the first time he has spread cheer. Last December, he had a jolly holiday when he celebrated his 90th birthday with a Mary Poppins flash mob. Try to suppress your tears as you watch his sweet video above.
