I like how the video is named "YOSHIKI X JAPAN", when it starts there is a caption with "SUGIZO X JAPAN" but is actually Heath interview, lol.
I have the We Are X with extras, this is in a Bonus Disc, along with short interviews with other members. Pata is also nice. Sometimes he tries to answer in english and is kinda funny.
Curiously he says that he was invited by hide to play in a studio with X when he was 21. This is 1989. There is some timeline break here.
