I don't know the answer to your first question.Originally Posted by seungheoney
For 3men & 3women (aka, guys and girls), there's DVD box for the entire 2 yrs of the show in Japanese for sale at http://www.takeshobo.co.jp/hang-ryu/guysn_girls_song/
Though I have a clip with English subtitle, I don't know where you can get the english subtitle version for the entire show.
When I have more time, I can check with seungheonplanet to see what they'd suggest. I want a copy too myself. Stay tuned ...
