T-ara was changed into Davichi?

T-ara recently appeared at Davichi’s concert as a guest and gave a surprise performance.

T-ara attended Davichi’s concert, ‘Adieu! 2011,’ which was held on December 27 at Olympic Park in Seoul. Davichi members appeared on the stage in retro style costumes and performed Lee Juk and Yoo Jae Seok’s “Apgujeong Delinquent.”

Then Davichi started singing T-ara’s “Roly-Poly.” Suddenly, the lights and the sound went out, like it was an accident. But in reality, it was a surprise performance. When the lights were turned back on, T-ara appeared on the stage.

T-ara sang their songs “Roly-Poly” and “Cry Cry” and received explosive applause from the audience.

Huh Gak also appeared at the concert as a guest and sang “Don’t Forget Me” from MBC’s series The Greatest Love and “Hello.”
