ROCKER Jimmy Barnes will undergo open heart surgery tomorrow to fix a condition that has been with him since birth.

The former Cold Chisel frontman will receive surgery to replace a faulty aortic valve.

A reformed alcoholic and party boy, Barnes entered hospital today and is said to otherwise be in good health.

Since the announcement of the operation a month ago, the Scottish born singer has honoured all appearance commitments.

On January 28, Barnes performed at the Australian Tennis Open in Melbourne, before heading to the United Kingdom for two shows.

One of the concerts held in Buckinghamshire on February 8 was a charity concert for cerebral palsy.

The rock legend is expected to make a full recovery.

Michael Gudinski, the head of Liberation Music and long-time friend, said the 50-year-old remained in high spirits.

"I'm sure, like myself, his legion of fans will be wishing him a speedy recovery," he said.
