Edgar Allan Poe may have died in 1849, but his influence is still felt in the horror genre today. Perhaps it was Poe that inspired today's spooky song by Fun Boy Three entitled The Lunatics (Have Taken Over The Asylum).
In 1845, Poe published the story The System Of Doctor Tarr and Professor Fether that was the inspiration for the same named song by the Alan Parsons Project on their Poe-inspired 1976 debut album entitled Tales Of Mystery And Imagination. The story concerns the odd happenings at a mental hospital where (spoiler alert for a 172-year-old book) the surprise twist is that the audience learns that the patients have switched places with the medical staff.
