A ghost in the machine

Video

Deep in the vaults of the EMI Archive lies a mysterious Ghostly Gramophone player. Despite laying dormant for many years, while showing visitors around the collection an unsuspecting intern and her guests witnessed the turn table revolving. The gramophone in question in not electric, no one had touched it and the winding mechanism is frozen.
We have video footage of the guests looking curiously at the turn table as the turn table continues to turn unassisted!
Is this paranormal activity or do you have a more scientific explanation?
