I've actually seen this video yesterday but wasn't able to finish cause I have another errand to do. Remember last January when wuri Hyun Joong tagged along with his hyung going to to Canada? You really don't see much of Leader here and some of shots actually blurred him, but still you can hear his voice.
If you can't see the video, go here.
