More than 40 carol groups will gather for an hour at a time under the big Christmas tree to fill you with festive cheer, and to raise money for charitable organisations. You can sign up to sing yourself too if you’re early enough—the organizers recommend having a group of at least 30 though.

If you’re not quite feeling festive yet, wrap up warm, join the crowds and bring some change for donations. Performances take place between 4pm and 8pm on weekdays and between 2pm and 6pm on weekends. There will be no performances on December 14th and 22nd.
