Dave Mustaine was asked by UG interviewer Justin Beckner on who would he have gotten to sing for Megadeth if he only played guitar in the band, to which he replied:
"I remember when I was in Metallica, we were all excited about John Bush - I think his singing was good for Armored Saint but I don't think it was, in the long run, what I would have wanted.
"Then Sean Harris, the former singer from Diamond Head - we were all in love with his voice. No one could sing better.
"But with that genius, sometimes comes lunacy and I think that when Diamond Head fell apart, most fingers point towards Sean.
"A lot of times frontmen - unless they have their head screwed on right - can be complete assholes.
"I remember when we were auditioning people - that was excruciatingly painful to deal with some of the personalities that came in.
Asked whether "any of the people who auditioned went on to join bands that our readers might know," Dave replied:
"Nobody that I know of."
