"A Dangerous Meeting" is the first song on the album "Don't Break The Oath" by "death metal" band Mercyful Fate.
At the time, the band's lead singer was King Diamond who looks like a cross between Alice Cooper, Marilyn Manson and KISS.
So he's definitely NOT to be confused with Neil Diamond!
King Diamond is also an admitted practicing Satanist.
That was probably one of the reasons why the guys at the record shop where I bought the album as a teen made comments the "questionable character" of KD.
It was also probably listening to music like THIS is what helped "contribute" to the rumors while I was in high school saying how I myself was a practicing Satanist.
