Kim Soo Chul (김수철) - Get a hold of yourself (정신차려) is the 1st Korean Music of the Day. This song was released in 1989 and the main chorus melody is quite famous and still used in different ways to response in a comedic way.
Jaurim did a recent cover of this song in "I am a Singer". I like a lot of songs that Jaurim did in the show, both their version and the original, but I personally like the original one better for this one. I think it's that awesome energetic dancing he does. :)
