After her three-hour long private funeral, Natalie Cole‘s family and friends gathered at Crustacean in Beverly Hills Monday night to celebrate her life.

Bobby Brown, Macy Gray, Mary Wilson and more performed while David Foster emceed the evening, hosted by Howard Grossman at one of Cole’s favorite restaurants.

“The mood was not somber, but an evening celebrating Natalie Cole’s life and her music,” says a source.

Cole’s son Robert Yancy also attended the event, and his grand-uncle Freddy Cole ended the evening with a performance of “It’s Easy to Remember (But So Hard to Forget).”

Others who attended included Quincy Jones, Diane Warren, Johnny Gill, Freda Payne, Eddie Levert and Keith Washington.

“I feel so blessed to have called you my friend, and my buddy, and many times my confidante,” Smokey Robinson said at Cole’s funeral Monday morning. “You are so real and down-to-Earth. Now I have to say you’re so real and up in heaven.”

Cole died Dec. 31 at the age of 65 from heart failure brought on by idiopathic pulmonary arterial hypertension, a rare lung disease.
