ZEROBASEONE's Sung Han-bin joins Gag Concert as guest singer, performs 'UNDEAD'
Six days after dropping his debut solo EP 'DEAD:ALIVE', Sung Han-bin takes the Gag Concert stage to perform 'UNDEAD' and show off his tutting skills.
Solo debut, then straight to the comedy stage
ZEROBASEONE's Sung Han-bin is the guest singer on KBS2's Gag Concert, airing October 18 at 10:35 PM. He appears in the Jeonbu Noraejang (All Singing Contest) segment alongside comedian Im Jae-baek. His first solo EP DEAD:ALIVE dropped October 12—six days before the taping, three years into the group's career.
He performs "UNDEAD" on the show and breaks out a tutting dance routine as a personal showcase. Tutting at a comedy show is a choice, and apparently it works.
Comedians back after 15 years, on trial for a forgotten album
The episode's other major segment is Gongae Jaepan (Public Trial), where comedians Kim In-seok and Yoon Sung-ho return to Gag Concert for the first time in 15 years. They've formed a trot duo called Kim Bbak (김빡) and released an album titled Jebi Han Mari.
Their comeback to the show is framed as a literal courtroom sketch. Judge Park Jun-hyung opens proceedings: "I will begin the trial for the crime of 'releasing an album that no one knows about.'" Defense lawyer Jung Beom-gyun counters that "'Kim Bbak' is a comedian who brightened Gag Concert before being a singer."
Kim In-seok also revisits his 2004 Gag Concert segment Do-Re-Mi Trio. Yoon Sung-ho performs a 2026 version of his signature catchphrase "Haji ma" ("Don't do it").
