Christy Dignam has admitted he’s started to constantly forget the words to his songs – and worries he has Alzheimer’s.
And the Aslan star can only remember the band’s most famous track because of an advertisement.
He said: “I feel like I have Alzheimer’s or something.
“I keep forgetting all the songs and parts of the songs – it’s really strange.
“The only reason I remember Crazy World is because of all those Laya Healthcare ads.”
And Christy – who is now due back on stage with the band in the Olympia – admitted he feared dying after being diagnosed with cancer.
He added: “I never thought I’d be on a stage again. I thought it was all over. So going back on stage will be brilliant.”
