A long ass time ago, I watched a show online called Dancing Brothers (which aired on Mnet) but up until today, I only knew it as Shindong's dance show, because that's how the user upped it on YT.
It starred him and a guy named Jaeyoung. They had to dance perfect choreography to various songs.
Anyways, I wanna see the show again, but have no idea where to find it. I've seriously been searching for 2 yrs (on and off, hehe). It was like the show never existed! Today finally decided to try some new search terms.
The only performance I can find online is U- go-Girl.
DBSK's Mirotic was online for a while, but that has been taken down.
The two of them have also danced to Nan Arayo and Replay.
