Brave Girls picked up guitars on the latest episode of 'Immortal Song'.

On part 2 of the 'married couple' special, the competitors were tasked with covering legendary artists Hong Seo Beom and Jo Gap Kyung as well as Kang Jin and Kim Hyo Sun. Brave Girls covered the 1980 track "It is Fire Play" by Hong Seo Beom's band Oxen 80, transforming themselves into a rock group. 

Minyoung and Yoojung stated, "We've never shown a rock side of ourselves. It's an honor just to be able to sing this song."

However, it was taekwondo athlete Na Tae Joo who took the final win.
