Doc, Thanks for the video.

The chorus should have taken a great effort and a long time to get it finished.

Obviously, the whole team is a dedicated group of international singers.

I am glad that you are there representing our homeland, Korea.

Some of the singers don't have the music folder in their arms or are they singers too?

In the second song (or rather a part), all of the singers have folded their music folder.

The second song seems to be an equally complicated song. But they do as well as the first song.

In the third song (Usk dalla), they opened the folder and read as they sing.

Why aren't they reading the music folder in the second song?

Please forgive me for my extreme ignorance in this particular art.

운영자님 감사합니다. 약 4 개월 연습합니다. 많은 사람이 음악 전공한 사람입니다.

앞의 두사람은 장님으로 노래를 잘합니다. 그리고 둘째 노래는 Kaki Lambe로

매우 단순하므로 모두 Memorize하여 부름니다. 가끔가다 손과 몸을 움직이는

Choreography를 할때도 Memorize 합니다.

Oh, my God...  I've never thought they were blind persons. ㅎ, ㅎ, ㅎ.

Kudos for them. Thanks for your reply to a stupid question of mine.
