Brown Eyed Girls' Narsha went for a retro theme with disco on March 30th's 'Immortal Song 2'.

She covered the well-loved hit by Lee Ja Yeon "[Flutter Flutter]" and went all out with the concept, wearing bell-bottoms and a short wig.

The MCs commented, "This is the first time we've enjoyed a performance in a party-like atmosphere like this." Despite her entertaining stage, however, Davichi took home the final win.
