Brown Eyed Girls' Narsha set off her journey as a solo artist recently with Bbi Ri Bop A and she is looking to continue the promotions. This sexy diva is not done quite yet, she has a follow-up song in the making! She just recorded her follow-up song Mamma Mia. In this song, "na na na na" is repeated just like how she kept singing "bbi ri bop a" in her first song. When the album was released a short version of the song was released as well. Now, the full version is awaiting its release. Fans have showed a positive feedback towards the song so it's definitely a wise choice. http://www.youtube.com/watch?v=qG2cbeAUSgU Narsha will end her promotions for BBI RI BOP A this weekend before taking a week off to promote with Brown Eyed Girls in Japan. After completion, she will return to Korea and promote Mamma Mia.
