Waving their LED-light signs and handmade posters with gusto, a group of fans scream their idol's name repeatedly.
It is behaviour typical of teenage girls at South Korean pop concerts - except that these fans are "aunties" in their 50s and 60s, and their idol is a getai performer.
The object of their affection is 32-year-old Hao Hao, the Singapore-based Taiwanese getai singer-host who is beloved as much for his lavish stage costumes as his ability to sing in both male and female voices.
The chatty bachelor, whose real name is Cheng Shih-wen, admits to Life! in an interview this week that he "never expected" this level of fanaticism, especially not in the getai world.
He says in Mandarin: "My fans may be older but they definitely do not lose out to teenagers at concerts."
He confesses to being "shocked" by his auntie-killer appeal. He muses: "I like to talk to older folks and I spend time chatting with them and I'll ask how they are. Maybe they like that about me. They treat me like a son or a grandson."
