For a special performance this week on 'Open Concert', the two 'The Unit' groups worked together to sing the survival program's theme song "My Turn". Despite this being the first time performing the song together since the program came to an end, the two groups looked flawless as a whole. Afterward, UNB had a chance to sing their recently released title track, "Feeling (Sense)" for everyone in attendance.

Check out both clips below!
