The American crooner, who had more than a dozen UK hits in the 1980s and '90s with songs like Criticize, has backed out of the show due to poor ticket sales.
He was due to appear on tonight's bill along with Kenny Thomas and Andy Abraham, as the headline act in their Decades of Soul tour, but the trio have had to cancel the entire tour.
