hey I've just found something out:
Do you know the song "Duel Beast" of D.T.R?
You remember on Shiroi Yoru, I don't remember correctly on which song it was, orgasm or X... hide played some notes on his guitar, Toshi listened to this and singed the same notes along with him.. something like "haheeehaaaaaaaaaaaahaa" lol.
Well.. the thing hide played is in a very very similar way in D.T.R's song Duel Beast also.
Perhaps hide listened to D.T.R ?..
The album which the song contains was released in 1994, so it really could have happened that he remembered a song of D.T.R while he was performing.
Please listen to that song, it's really damn similar, if not, identical (identical on: 2:10 min in that song.. similar notes in the whole song).
check it out!
