Sensational performer Byrne, originally from Dublin’s Drimnagh, had emigrated to Sydney at the age of 25 in the late ’80s with his then Irish girlfriend.

However, Peter’s dream of a new life fell apart when his relationship broke down. “The girl I was with ran off with somebody,” he tells the Sunday World today.

I was pretty much close to packing up and going home. Then one night a neighbour of a mate of mine, who I moved in with, invited me to join him at a pub in the city where he was meeting a friend who worked there.

“The friend was singing there from 10pm to two in the morning and he said to me, ‘I hate this job, I’m too old for it, do you want my job?’ He was 60. He knew I sang, but he’d never heard me singing.

“He called the manager down and told him, ‘This guy is Peter Byrne, he’s very good. I’m quitting, I can’t do these late nights anymore.’ So the manager gave me a two-week trial.

“I immediately bought a sound system and a decent guitar and I learned four hours of material… all the sing-a-long songs. After two weeks I had the place hopping. I never looked back.

The affable Dubliner, now 62, admits he couldn’t believe his good fortune when his career took off into the stratosphere after he stumbled into the music of Love On The Rocks singer Neil Diamond.

“They talk about the luck of the Irish and I do think it exists,” Peter laughs.

One of the jobs I had was working in a restaurant as a singer and musician playing in the background. One night a guy said, ‘Do you know the Neil Diamond song, I Am… I Said?’ I didn’t know it, but I went off and learned it and when he came back the following week with his wife I sang it.

“Within four minutes the entire restaurant had stopped eating, people looked up and they just went crazy at the end. Afterwards, the guy said, ‘Do you realise how much you sound like Neil Diamond? You are so close, you should just work on the Neil Diamond stuff.’ And that’s how it happened.”
