A`ST1 Info xD

“The 6-male group is called A’ST1 and is composed of Korean members Park Jung Jin (22), Byun Jang Moon (21), Sung In Kyu (21) and Lim Han Byul (20), Japanese member Tomo (22) and Chinese member Haiming (22). A single will be released at the end of March or in April,” DSP revealed on March 3. The single’s title track is called “1234Back,” which was composed by Han Sung Won, the one who made Park Ji Hun’s “The Day I Miss You.”

They also sang "Yearning of the Heart" for the popular "Boys Over Flowers" drama because they were under the same entertainment as Kim Hyunjoong [Yoon JiHoo]. Also, Haiming had a cameo role in Boys Over Flowers acting as a gay friend of Yoon JiHoo.

Their comeback performance was on April 17th. Their song was called "Dynamite". It's pretty catchy.

A’ST1 disbanded on 29th November 2009.
