Super Junior-T re-released this single in Japan on November 5, 2008, collaborating with the Japanese female comedy duo, Moeyan.

The music video features fellow label mate Isak as a comedic rabbit who was playing Whack A Mole with the members as the targets.

Although trot music are usually more accepted by the older audience because of its older style of korean popular music, Super Junior-T's "Rokkugo" has been well-accepted by young audiences as each track in the single are bending more towards a new style of trot to attract the attention of the young audience, hoping to make traditional trot music more accepting in mainstream music.

"Rock & Go" is the Japanese version of "Rokkugo", and was released in Japan on November 5, 2008.

The single debuted at #19 on the Oricon Daily Charts[4] and jumped to #2 three days later.
