Jakarta. At least 60,000 fans are expected at a free concert called "Konser Gue 2" (My Concert 2) held in support of incumbent Jakarta Governor Basuki "Ahok" Tjahaja Purnama and his running mate Djarot Saiful Hidayat in their re-election campaign in Senayan on Saturday (04/02).

The deputy chairman of Ahok-Djarot’s campaign team, Bambang Waluyo Wahab, said more people might turn up as the day goes on.

"60,000 is what we expect on paper," Bambang said on Saturday.

The concert's organizer will deploy 670 security personnel at the concert, assisted by hundreds of officers from the Jakarta Police.

"We're working together with the police to keep the concert safe. It's up to the police how many officers they will have there," Bambang said.

High-profile politicians expected at the concert

Several high-profile politicians who are backing Ahok-Djarot have said they will also attend the concert, including Indonesian Democratic Party of Struggle (PDI-P) Chairwoman Megawati Soekarnoputri, Golkar Party Chairman Setya Novanto, Nasdem Party Chairman Surya Paloh and Hanura Chairman Oesman Sapta Odang.

"Setya Novanto will come with [politicians] Agung Laksono and Theo Sambuaga. Surya Paloh from Nasdem and Oesman Sapta from Hanura will also attend," Bambang said.

Musicians and celebrities booked to perform in the concert include Slank, Marcello Tahitoe, Tompi, Once, Dian HP, Sandhy Sandoro, Kikan, Krisdayanti, PMR, Dira Sugandi, Shanty, Gita Gutawa, Project Pop, Happy Salma, Zastrouw Al Ngatawi & Orkes Kiganjur, Iwa K, Ernest Prakasa, Desta, Yossie, Indy Barends, Melanie Ricardo and more.

Jay Subiakto and rock band Slank, the event's originators, had held a much bigger concert for President Joko "Jokowi" Widodo during his presidential campaign in 2014 at the Gelora Bung Karno stadium.
