Hit composer Brave Brothers recently guested on a recording of KBS's 'Win Win' and revealed a behind-the-scenes story of how he came up with Son Dambi's mega-hit, "Saturday Night". Brave Brothers revealed, "Up to this point, I've made the most royalties from 'Saturday Night'. Quite honestly, I made the song in about 10 minutes, and I was also the one that came up with the idea for her choreography. I was wearing just my boxers at home when I came up with it and I got so excited that I called up the company CEO and director to my home and showed them the dance in my underwear." Fellow composer Shinsadong Tiger added, "I also came up with the point dance in 'Roly Poly'. I showed it to them on the spot." The full episode will air at 11:15 PM KST on November 25th.
