Vocal group SG Wannabe will rmake a long-overdue comeback later this month.

"SG Wannabe will release an album in mid-August. The new title track is composed by Jo Young Soo," commented a source from agency CJ E&M.

"He composed a track that sounds even better than his previous SG Wannabe tracks such as 'Timeless' and 'Partner for Life.' All the SG Wannabe members love the track. This track will truly mark the return of the ballad legends," he added.

SG Wannabe's comeback will end the group's 4-year hiatus which began with the members' military enlistment in 2011. The group then decided to make a comeback after discharge and signed a contract with CJ E&M in early 2015.

With the collaboration of Jo Young Soo and CJ E&M, curiosity is rising over what kind of influence SG Wannabe will make in the music world this summer.

SG Wannabe will officially return on August 18.
