Singer Neil Diamond down with Parkinson’s Disease

Neil Diamond, one of the best-selling singers of all time, has announced he is immediately retiring from touring after being diagnosed with Parkinson’s disease.

He made the announcement on his website on Monday.

The onset of the disease has made it difficult for him to travel and perform on a large-scale, a statement on the site said, adding he will be cancelling upcoming concert dates in Australia and New Zealand and offering refunds.

“It is with great reluctance and disappointment that I announce my retirement from concert touring. I have been so honoured to bring my shows to the public for the past 50 years,” Diamond said in the statement, offering apologies to those who purchased tickets to his upcoming shows.

Diamond, known for hits including “Sweet Caroline” and “Cracklin’ Rosie,” said he plans to remain active in song writing and recording.

Later this week, Diamond will turn 77 and on Sunday the Recording Academy plans to honour him with its Lifetime Achievement Award.

Diamond has sold more than 130 million albums worldwide and 38 of his singles have made it to the Top 40, according to the academy.
