Davichi covered Kang Jo Han's "Tatata" in their own tango style on the November 9th episode of 'Immortal Song 2'.
As expected from the vocalist duo, the other singers had nothing but praise for their performance. The competitors in the waiting room commented, "They showed the truth." Kim Kuk Hwan also said, "I practiced this song for a year, and I can tell that Davichi did a lot of research. I really adore them."
