Ahmad Pathoni – About 50 Indonesians staged a flash mob on Sunday to demand that Lady Gaga be allowed to perform in the country amid uncertainty about her scheduled concert in Jakarta.

The police announced last week it would not issue permit for the June 3 concert, citing objections from conservative Muslim groups who deem her stage act to be "incompatible with Indonesian culture." Promoters said they were negotiating with the police to allow the show to go ahead.

Fans performed Lady Gaga's dance moves at the National Monument Square and unfurled a banner saying "Indonesia Wants Lady Gaga," during an event that organizers described as "a flash mob."

"I and thousands of other fans are disappointed by the police's decision to ban Lady Gaga's concert," said Simon, who took part in the event. "Lady Gaga is harmless because she's just an artist," he added.

About 50,000 tickets have been sold for the concert at the Bung Karno national stadium, part of Gaga's Born This Way Ball tour.

A cabinet minister has waded into the controversy and called for a compromise. "Maybe the concert can be adjusted to Indonesian culture," Coordinating Minister for Law, Politics and Security Djoko Suyanto was quoted as saying by the Kompas daily on Saturday.

Conservative Muslim groups said Gaga's "pornographic" stage act could poison the morals of the country's youth. The Islamic Defenders' Front, a group known for sometimes violent campaigns against vice, had threatened to block the gig.

Gaga, whose real name is Stefani Germanotta, is known for her eccentric and risque outfits in videos and on stage.

International acts are flocking to Indonesia, the country with the largest Muslim population in the world, to take advantage of its strong economy and a growing middle class with disposable income.

In the past year, pop stars such as Katy Perry, Justin Bieber and Kylie Minogue have performed in Indonesia without incident.
