Medium and clairvoyant Andrew Beasley was due to host the event at Arksey's Old School Tea Rooms on July 21 - but the event has been shelved.
A spokesman for The Old School Tea Rooms said on Facebook: "Due to unforeseen circumstances, the Andrew Beasley evening is unfortunately cancelled.
"We apologise for the inconvenience and if you have purchased tickets you can collect a full refund. We will be rebooking later in the year."
Mr Beasley's Facebook page describes him as a "very talented local medium and clairvoyant known for his accuracy with dates and full names."
