Lee Jun Young has made his first public stage appearance since beginning his mandatory military service, and his surprise performance has given fans a glimpse of the actor and former U-KISS member in uniform. He appeared at a local festival as part of the 35th Infantry Division’s military band, where he sang and even showed off his dance skills.

The appearance took place on September 13 at the 20th Jangsu Korean Beef and Apple Festival in Jangsu County, North Jeolla Province. Wearing the band’s red uniform with white trousers, Lee looked noticeably different from his pre-enlistment appearances, sporting a closely cropped haircut and a slightly fuller face.

Lee Jun Young Performs With Military Band

Lee Jun Young appeared onstage as a member of the 35th Infantry Division’s military band during the festival’s celebratory performance. While his military role required a disciplined appearance, the actor quickly showed his natural stage presence once the music began. He performed several songs during the event, including J.Y. Park’s “Honey,” for which he also performed the choreography.

Footage from the performance showed Lee initially standing alongside his fellow band members before loosening up and dancing energetically as the song progressed. His ability to sing while performing the choreography also drew attention, particularly because Lee has had fewer opportunities to perform onstage since establishing himself primarily as an actor.

From U-KISS Member To Military Band Performer

Lee Jun Young originally debuted as a member of U-KISS in 2014 before expanding his career into acting. Over the years, he became known for appearances in dramas and films, including D.P., Mask Girl, The Impossible Heir, Melo Movie and Weak Hero Class 2.

His surprise military-band performance therefore brought back a part of his idol career that audiences have not seen as frequently in recent years. Videos recorded during the festival were shared across social media and online communities, where his performance and appearance quickly attracted attention. The stage also highlighted how naturally he transitioned between his military responsibilities and his long-established experience as a performer.
