The reclusive Northern Irish singer insists modern singers don't know what real R&B is.

He tells the Sunday Mail newspaper, "I can't relate to it now, what they call R&B. It doesn't have any blues. To me, it is very unrhymitic. It's very robotic. That's what happens, the words take on different meanings after a while. It's like the word spiritual. What does that mean? It could mean anything now....

"It's like soul; I don't know what that is now. To me, soul was Ray Charles, Sam Cooke, Bobby Bland, Solomon Burke, Bobby Womack. But what is it now?"
