britney-spears.jpgStormy weather that is expected to continue to drench the Bay Area this weekend has forced Britney Spears’ outdoors concert in San Francisco inside.

The pop superstar’s concert was suppose to be at the Castro Theatre on Sunday. It now will be at the Bill Graham Civic Auditorium, located at 99 Grove St.

The free, hour-long performance will air Tuesday on ABC’s Good Morning America to coincide with the release of Spears’ latest album, “Femme Fatale,” according to the network.

Tickets are required for the concert, which begins at noon. Ticket information will be available at after 9 a.m. Thursday.

As noted by ABC7, tickets for the “free” show aren’t quite free, as:

The 5,000 tickets for the show are free, but Ticketmaster will charge a $3.50 service fee. Each person can request up to a maximum of four tickets. All tickets are general admission and will contain a specific barcode that the theater will scan to make sure it’s legitimate. Everyone who gets a ticket must print it from home and bring it with them. No tickets will be distributed on site or be available at will call. Doors will open at 10:30 a.m. PT.

Update: A Ticketmaster spokesperson informs the Appeal that ABC7 was mistaken, and says that “no fees were charged for this event.” We regret repeating ABC7’s error, and appreciate Ticketmasters’ contacting us with this correction.

Not that it matters to you, necessarily — according to SFist, tickets were sold out in minutes.

Local Castro retailer Under One Roof, whose proceeds go to HIV/AIDS research, is celebrating all week by displaying a Spears wax figure from the Wax Museum at Fisherman’s Wharf.

Patrons who pay a suggested donation can be photographed with the figure, and on Friday evening, the retailer, located at 518 Castro St., is hosting a Spears look-alike contest.

Supervisor Scott Wiener is scheduled to judge the contest, said David Perry, one of Under One Roof’s founders.

All proceeds collected by Under One Roof will go to charitable contributions, Perry said.

“Any time a star of this magnitude comes to San Francisco it just proves what we already know: San Francisco is a wonderful hub for culture and pop music,” Perry said.

He added that Spears has been “incredibly supportive” of the LGBT community, and that featuring her wax figure is a way to thank her for her work and draw attention to Under One Roof’s mission.

“I think I know exactly where I will be Sunday morning–along with thousands of other people,” he said.
