Legendary singer Neil Sedaka’s cause of death revealed

Neil Sedaka, the iconic crooner behind hits like “Calendar Girl” and “Love Will Keep Us Together,” died of atherosclerotic cardiovascular disease, the Post has learned.

The disease is a chronic condition caused by the buildup of fats, cholesterol and other substances in artery walls, often resulting in a heart attack.

Kidney failure also contributed to his passing in Los Angeles late last month at 86 years old, according to a death certificate obtained by The Post.

The hitmaker’s occupation was listed as a singer and songwriter. The certificate also states he was embalmed at the Hollywood Funeral home and buried at Beth Olam Cemetery in LA on March 3.

The Brooklyn-born singer died at Cedars-Sinai Medical Center in Los Angeles on February 27.

The performer is best known for releasing multiple No. 1 hits in the 1960s, including “Breaking Up Is Hard to Do.”

He was nominated for five Grammys between 1959 and 1977 and was subsequently inducted into the Songwriters Hall of Fame.

Prior to Sedaka’s solo career taking off, he got his start as a member of The Tokens in the 1950s — years before the doo-wop group blew up with “The Lion Sleeps Tonight.”

He had been married to wife Leba Strassberg since 1962.

The couple share two adult children — daughter Dara, a 62-year-old vocalist, and son Marc, a 59-year-old screenwriter.
