Tonight is the first of the Big Top shows. It's always great to play in Sydney. A lot of my guys will come forward….I've been waiting for this for a long time,' he said on Instagram.

'Thanks to Karen Lee Andrews and The Cruel Sea for warming up the crowd. I'm ready.'

Dubbed 'The Big Five-0', the Cold Sisal 50th Anniversary Tour has already sold over 150,000 tickets across 16 shows, making it one of the most anticipated Aussie tours of the year.

He returned to the stage just weeks after being forced to postpone two months' worth of shows as he recovered from an emergency 'remedial' hip operation.

In a heartfelt message on Facebook at the time, Jimmy explained the unexpected need for surgery at the time and apologized to fans for the postponement.

As I was leaving Dunedin I sprained my hip and by evening the pain was excruciating. Doctors are moving fast, but I am expected to make a full recovery in six weeks,” he shared.

To help him recover from home, a peripherally inserted central catheter (PICC) tube was implanted in his arm to deliver medication to the large blood vessels around his heart.

In late September, Jimmy took to Instagram to celebrate having his PICC line removed after a six-week recovery.

“I was able to leave the hospital and continue most of my recovery at home,” he said. It is simultaneously restraining and liberating.

'With the help of doctors, nurses, physiotherapists, family, friends, you and my Jane, my recovery is now over.'

By the time he was wheeled into the operating theater for open-heart surgery, his doctors told him he had only hours to live.

In a marathon seven-hour surgery, doctors successfully replaced his damaged valves and repaired his heart.
