Neil Diamond sang ‘Sweet Caroline’ in a rare public appearance at the weekend while at a Red Sox game at Fenway Park in Boston.

According to Billboard, the 81-year-old singer retired from touring in 2018 after being diagnosed with Parkinson’s Disease.

At Saturday’s Red Sox game, he came out to sing his 1969 hit during the 8th inning of the game against the St. Louis Cardinals.

He last performed at Fenway Park almost a decade ago in 2013, where it’s reportedly been a tradition to play ‘Sweet Caroline’ during the 8th inning since 1997.

Alongside Diamond was actor Will Swenson, who plays the lead role in A Beautiful Noise, The Neil Diamond Musical.

“Hands, touching hands/Reaching out, touching me, touching you/Sweet Caroline/Good times never seemed so good,” the duo sang together as the game attendees joyfully sang and danced along.

Diamond announced his retirement in 2018 after cancelling dates in Australia and New Zealand due to his Parkinson’s diagnosis.

“I plan to remain active in writing, recording and other projects for a long time to come,” he wrote. “This ride has been ‘so good, so good, so good’ thanks to you.”
