From Lexpecto Patronum:

The Winter Wizarding Waltz celebrates its fifth anniversary with our biggest event yet! An immersive wizarding village with live entertainment, food stalls and handcrafted market. The annual event has become an experience like none other, incorporating a new thematic aspect of the Harry Potter universe at each event. This years theme is: The Sweet Soiree. It is Lexpecto’s only fundraiser for the organization itself and finances all of the outreach done through the club.

MMMB performs at 6:30pm.
