It could only happen in the world of heavy metal

 Motley Crue's Nikki Sixx was allegedly replaced by a doppelganger called Matthew Trippe.

Trippe claimed that he replaced Nikki Sixx in 1983 after he ended up in hospital. He made his claims from 1988 to 1993, then disappeared. It made for a pretty big story in Kerrang! if I remember rightly.

There’s the old chestnut about Ozzy biting the head off a bat.

During the Diary of a Madman tour, part of the show involved offal being thrown over the crowd, so there were lots of this strewn around the stage. Ozzy thought the bat was either part of the offal or a plastic one, and bit the head off. Ozzy later said the bat was alive and bit his tongue, leading to the double O needing a rabies shot.

Judas Priest’s music played backwards

Judas Priest’s music was allegedly the cause for two of their fans killing themselves. Weirdly, the accusation was that if the record was played backwards, it would then say ‘do it.’ The was taken to court, and proved to be bollocks.

These stories were all true.

In fiction, Cold Steel went on a treasure hunt in the Caribbean, and ended up nearly starting a war. Thankfully, live metal came to the rescue, as always.
