The performance gave audiences a chance to see the West End cast live before they take to the stage next year.
Originally scheduled to open in April 2020 and then initially moved to September, the piece will now begin performances on 22 April 2021 for a 19-week run.
The piece is set to star Michael Ball and Paul Merton, with Ball reprising his award-winning role as Edna Turnblad and Merton making his West End musical debut as Wilbur Turnblad. They will be joined by a cast including Lizzie Bea as Tracy Turnblad, Rita Simons as Velma Von Tussle, Jonny Amies as Link Larkin and Marisha Wallace as Motormouth Maybelle.
Hairspray the Musical is based on the 1988 film of the same name, which starred Divine and Ricki Lake.

The original London production in 2008 won four Olivier Awards.
