Neil Diamond has canceled his upcoming tour and announced that he's retiring from the road, because he was recently diagnosed with Parkinson's disease.

Neil will turn 77 tomorrow and last April, he launched a massive 50th anniversary tour, which included more than 50 shows in North America and Europe.  On top of that, he only took a month off between the two legs.

He was supposed to travel to Australia to begin the third leg in March, but those concerts have been canceled.  Neil put out this statement, quote:

It's with great reluctance and disappointment that I announce my retirement . I plan to remain active in writing, recording, and other projects for a long time to come.  My thanks goes out to my loyal and devoted audiences around the world, this ride has been 'so good, so good, so good' thanks to you. - Neil Diamond

Neil will get a Lifetime Achievement Award at the Grammys on Sunday.  He also rang in the New Year by leading a massive sing-along of "Sweet Caroline" in Times Square.  It's unclear when he was diagnosed.
