CHUNG HA and Christopher have joined forces once again.

On Thursday (20 October), the South Korean vocalist and Danish pop sensation released their new collaborative single, 'When I Get Old’. 

Coming two years after the launch of their first joint project, 'Bad Boy', the track is a marriage of different genres that evokes feelings of nostalgia. 

“No one goes through life and feels happy every single day. But if you choose to focus on the good times — both the big events and also the little seemingly uneventful situations that add color to your everyday life — I’m convinced you’ll be happy right here, right now and when you look back on the day you get old. ‘When I Get Old’ is a celebration of nostalgia and a life of happiness,” explained Christopher.

When the time came to decide who to bring on board for the song, the 30-year-old only had one artist in mind.

He shared: “She’s such an amazing, gifted artist and the release of ‘Bad Boy’ during the pandemic was a challenging but giving experience for both of us. Now, with the world back on its feet, it just feels right to finally be working with CHUNG HA again.”

Christopher and CHUNG HA were recently reunited at the former's sold-out August concert in Seoul, during which they treated the audience to a special live rendition of 'Bad Boy'.
