During the making of Rainbow's Long Live Rock 'N' Roll album in 1977, frontman Ronnie James Dio claimed to have experienced some particularly intense paranormal interference from a "really evil spirit" that would not only try to sabotage their creative efforts, but pose a real danger to their lives.
In fact, the legendary late singer even accused the entity, known as 'Baal', of having pushed his wife Wendy down the stairs - a moment which would contribute to Dio's reluctance to "meddle" with the spirit world in the future.
