Last month we revealed that singer Kim Jong Gook would be celebrating his 15th year anniversary as a singer through a solo concert titled 2010 Kim Jong Gook Most Wanted Concert. It's now been reported that Haha will be making his return to the k-pop scene as a singer after 2 years through Kim Jong Gook's concert! Haha was recently discharged from the army after his two year mandatory military service. Now that he's back, he's been slowly easing his way into variety programs to make his comeback. But it looks like all that is leading up to Haha's big comeback as a singer at the concert. It has also been revealed that Haha and Kim Jong Gook will perform a duet together, so it looks like things are going to be a lot more interesting. After all, when you put these two together, only hilarious fun and great entertainment can be the result. http://www.youtube.com/watch?v=MjrOls0DtHo
